Deloitte Interview Process

The Deloitte interview process typically consists of two rounds of interview that include case interviews, a group case interview, and behavioral or fit interview questions. The entire interview process can take anywhere from one week to a few months.

Given its size, Deloitte may have a different interview process depending on the country or the office that you are interviewing for. However, the most common interview process consists of two rounds of interviews following the submission of your Deloitte resume .

• First round interviews : you will have one 30 to 45-minute behavioral interview and one or two 30 to 45-minute case interviews.
• Final round interviews : you will have a 30 to 45-minute behavioral interview, a 30 to 45-minute case interview, and a one hour group case interview

There are three important distinctions between your first round Deloitte interview and your final round Deloitte interview.

One, your interviewers will likely be more senior people at Deloitte. This means that the case interviews you receive may be a bit less structured and more qualitative in nature. The case interview may feel more like a discussion where you and the interviewer are discussing your opinions and ideas on a business problem.

Two, there will be more of an emphasis on assessing your fit with the firm. The first round interview is primarily used as a screener to determine whether or not you can solve case interviews effectively and whether or not you have the potential to be a great consultant.

Final round interviews will also continue to assess this, but interviewers will also be determining whether or not you would be a great fit with the office. Are you coachable and easy to work with? Are you collaborative? These are a few of the qualities that interviewers want to see.

Three, your interviewers may read the notes that your interviewers wrote during your Deloitte first round interview. If there was a particular area of the case interview that you struggled with, interviewers may want to test you again on it to make sure that it is not a significant weakness.

What is a Deloitte Case Interview?

A Deloitte case interview, also known as a “case” for short, is a 30 to 60-minute exercise in which you and the interviewer work together to develop a recommendation or answer to a business problem.

These business problems can be anything that real companies face:

• How can Amazon increase its profitability?
• What can Apple do to increase customer retention?
• How should Tesla price its new electric vehicle?
• Where should Disney open another Disneyland theme park?

Deloitte case interviews simulate what the consulting job will be like by placing you in a hypothetical business situation. Cases simulate real business problems that consulting firms solve for their clients. Many Deloitte case interviews are based on actual projects that interviewers have worked on.

While consulting projects typically last between 3 to 9 months, case interviews condense solving the business problem into just 30 to 45 minutes.

Deloitte case interviews can cover any industry, including retail, consumer packaged goods, financial services, energy, education, healthcare, government, and technology.

They can also cover a wide range of business situations, including entering a new market, launching a new product, acquiring a company, improving profitability, and growing revenues.

Although Deloitte case interviews cover a wide range of industries and business situations, no technical or specialized knowledge is needed. Unless you are interviewing for a consulting firm that specializes in a particular industry or function, cases are designed to be solved by someone that has general business knowledge.

Nailing your Deloitte case interviews is critical to get a job at Deloitte. There is no way to get a Deloitte job offer without passing your case interviews.

What Does a Deloitte Case Interview Assess?

Deloitte case interviews assess five different qualities or characteristics: logical and structured thinking, analytical problem solving, business acumen, communication skills, and personality and cultural fit.

1. Logical and structured thinking : Consultants need to be organized and methodical in order to work efficiently.

• Can you structure complex problems in a clear, simple way?
• Can you take tremendous amounts of information and data and identify the most important points?
• Can you use logic and reason to make appropriate conclusions?

2. Analytical problem solving : Consultants work with a tremendous amount of data and information in order to develop recommendations to complex problems.

• Can you read and interpret data well?
• Can you perform math computations smoothly and accurately?
• Can you conduct the right analyses to draw the right conclusions?

3. Business acumen : A strong business instinct helps consultants make the right decisions and develop the right recommendations.

• Do you have a basic understanding of fundamental business concepts?
• Do your conclusions and recommendations make sense from a business perspective?

4. Communication skills : Consultants need strong communication skills to collaborate with teammates and clients effectively.

• Can you communicate in a clear, concise way?
• Are you articulate in what you are saying?

5. Personality and cultural fit : Consultants spend a lot of time working closely in small teams. Having a personality and attitude that fits with the team makes the whole team work better together.

• Are you coachable and easy to work with?
• Are you pleasant to be around?

All of these five qualities can be assessed in just a 30 to 60-minute Deloitte case interview. This is what makes case interviews so effective in assessing consulting candidates.

How to Solve Deloitte Case Interviews

Deloitte case interviews are candidate-led. You will be in the driver’s seat of the case interview and will be expected to ask the right questions, probe for data, and propose each next step to solve the case.

In a Deloitte case interview, you are not assessed on whether or not you have the correct answer. Instead, Deloitte uses case interviews to assess six different qualities:

• Problem solving : Can you decompose a problem into smaller, more manageable questions?
• Analytical ability : Can you draw the right insights from data and information?
• Strategic thinking : Do you have a sharp business acumen and practical business judgment?
• Logical thinking : Are you structured, organized, and rational in the way that you think?
• Creativity : Can you generate interesting or unique ideas and solutions?
• Professional demeanor : Are you calm, confident, and articulate?

Our step-by-step guide to case interviews is presented in the video below. We highly recommend watching that video in its entirety. 

On Deloitte's case interview website , they recommend taking five   steps to solve a case interview:

1. Understand the issue and ask clarifying questions

The most important part of the case interview is to make sure you understand the business issue and the objective of the case. The quickest way to fail a case interview is to answer or address the wrong business problem. 

Therefore, if either the business issue or objective of the case is unclear, make sure to ask clarifying questions.

2. Identify the underlying assumptions

Next, you’ll need to decompose the overall business problem into smaller, more manageable issues. Identify what would need to be true in order for you to recommend a particular course of action.

To do this, it will be helpful to put together a framework, which is a tool that helps you organize your ideas and thoughts into different categories. For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks .

3. Summarize specific issues and findings

Afterwards, you’ll begin investigating different issues or areas of your framework. After investigating each one, it is important that you summarize the key takeaways or insights that you uncovered.

Connect these findings back to the overall business problem and explain how your findings impact your potential recommendation.

4. State your recommendations

Once you have gathered enough evidence and support for your recommendation, you will need to present your recommendation in a clear and concise way.

Start by giving a firm recommendation. Then, provide the three major reasons that support your recommendation. This should summarize most of the important findings from the case.

5. Outline next steps and the expected results or impact

After delivering a recommendation, you should propose potential next steps that you would take if you had more time or data. What would you need to know to further strengthen your recommendation or make you more confident in your answer?

You can also talk about the expected results or impact of your recommendation. This may also have implications on potential next steps, such as analyzing the risks or quantifying the financial benefits. 

The Different Types of Deloitte Case Interviews

There are three different types of Deloitte case interviews, one type for each of Deloitte's consulting groups:  

• Strategy & Operations : primarily focused on corporate strategy, supply-chain improvement, business model transformation, and process improvements. The work that this group does is most similar to the work that McKinsey, BCG, and Bain do
• Business Technology : primarily focused on digital strategy, delivery of information technology programs, and building tech-based solutions for clients
• Human Capital : primarily focused on organization transformation, change management, corporate learning and development, and diversity and inclusion

The type of case that you get depends on what group you are interviewing with. 

For example, If you are interviewing with the Strategy & Operations group, you’ll get a strategy or operations case . You may be asked to determine whether to enter a new market, launch a new product, or make an acquisition.

If you are interviewing with the Technology group, you’ll get a technology or IT case. You may be asked to determine whether to roll out a new IT system, how to assess different technologies, or how to best coordinate an IT transformation.

If you are interviewing with the Human Capital group, you may be asked to determine the optimal organization structure, how to better incentivize employees to perform better, or how to save payroll costs.

  Deloitte Case Interview Tips

Below are eight of Deloitte's case interview tips to help you improve your case interview performance.

Tip #1: Take notes

While the interviewer is providing you with the case background information, take notes on the most important pieces of information. Pay particularly close attention to the context, company, and case objective.

Tip #2: Make sure you understand the case question

Answering or addressing the wrong business problem is the quickest way to fail a case interview. The most important thing is understanding what the business issue is and what overall question you’ll be expected to answer at the end of the case. 

Tip #3: Ask questions

Do not be afraid to ask questions. You will not be penalized for asking questions that are important and relevant to the case. 

Great questions to ask include asking for the definition of an unfamiliar term, asking questions that clarify the objective of the issue, and asking questions to strengthen your understanding of the context or company.

Tip #4: After you develop a framework, develop an initial hypothesis

A hypothesis is an educated guess on the answer based on the data and information that you have so far. It helps guide your analysis and keeps you on the right track.

After developing a framework, try to develop a hypothesis to help you decide what area of your framework you should explore first.

Tip #5: Take time to structure your thoughts

When asked a question in a case interview, don’t always start answering immediately. Instead, take the time to process the question and develop an organized and structured way to answer it. It is acceptable to ask the interview for a brief moment to collect your thoughts.

Your answer will likely be much stronger if you give yourself time to think. 

Tip #6: Present a clear, logical story for your recommendation

Remember that consultants need to convince clients to follow their proposed recommendations. Being articulate and persuasive are necessary skills for consultants.

When you deliver your recommendation, try to make it a coherent story. This will make your recommendation easier to follow and more compelling.

Tip #7: Walk the interviewer through your thinking and explain assumptions

You do not get any points for the ideas and thinking that you do not communicate. Therefore, you should make every effort to talk through your thoughts out loud.

Walk the interviewer through what you are thinking. Explain why you have made particular decisions. State your assumptions. This makes it easier for the interviewer to provide feedback or hints to help you out.

Tip #8: Engage the interviewer in a business conversation

Remember that a case interview is a collaborative exercise. You should not be dismissing the feedback and suggestions that the interviewer provides you. They may be trying to help steer the case in the right direction or provide you with hints when you get stuck.

Treat the interviewer as your teammate and turn the case interview into a business conversation.

How to Prepare for Deloitte Case Interviews

There are seven steps to preparing for Deloitte case interviews.

1. Understand what a case interview is

The first step in preparing for Deloitte case interviews is to understand exactly what case interviews are.

When you are familiar with what case interviews are, it is important to know what a great Deloitte case interview performance looks like.

Knowing what a great Deloitte case interview performance looks like will facilitate how quickly you learn case interview strategies in the next step.

Before continuing onto the next step, you should be familiar with:

• The overall objective of a case interview
• The structure and flow of a case interview
• The types of questions you could get asked
• What a great case interview performance looks like

2. Learn the right strategies

Now that you have sufficient background knowledge, the next step in preparing for Deloitte case interviews is to learn the right strategies to build good case interview habits.

It is much more effective to learn the right case strategies the first time than to learn poor strategies and try to correct them later.

The quickest, most efficient way to learn these strategies is to go through our Comprehensive Case Interview Course .

If you prefer reading case interview prep books instead, the three I recommend are:

• The Ultimate Case Interview Workbook
• Case Interview Secrets

Hacking the Case Interview provides strategies on exactly what to do and what to say in every step of the case interview. It is a concise and straight to the point guide. I recommend this book as the first book to read for beginners.

Case Interview Secrets teaches core concepts such as the issue tree , drill-down analysis, and a hypothesis driven approach. It illustrates these concepts through stories and anecdotes. If you have read Hacking the Case Interview, I recommend also reading this book to get perspectives from a second author. Check out our full review of Case Interview Secrets .

Case in Point provides a ton of specific and complex frameworks. However, you likely won’t be using many of these in an actual case interview because many of them are overly complex and specific. If you have time, it may be useful to skim through this book. Check out our full review of Case in Point .

At the bare minimum, read either the first or second book. If you have the time, read the first two books so that you can get strategies from two different authors.

Make sure to spend sufficient time learning the right strategies before starting to practice cases. It is ineffective to practice cases if you have no idea what strategies to practice and refine.

Before moving onto the next step, you should at least have strategies for the following parts of a case interview:

• Developing unique and tailored frameworks
• Solving quantitative problems
• Answering qualitative questions
• Delivering a recommendation

3. Practice 3-5 cases by yourself

Once you have learned the right strategies, the next step in Deloitte case interview prep is to practice.

When practicing case interviews, it is usually better to practice with a case interview partner than to practice by yourself . Casing with a partner better simulates the real case interview experience.

However, when you are just starting to practice, I recommend doing the first 3 – 5 cases by yourself.

There are three reasons for this:

• You can get the hang of the case interview structure and format much more quickly working by yourself rather than having to wait to schedule a time with a partner
• There are many aspects of case interviews that you can practice without a partner, such as structuring a framework and solving quantitative problems. You can get much more practice working through these parts by yourself
• You may have difficulty finding a case interview partner if you are a complete beginner. Without having done any cases, you likely won’t know how to properly give a case or provide good feedback

4. Practice 5-10 cases with a partner

The next step in preparing for Deloitte case interviews is to case with a partner.

Casing with a partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner.

When practicing cases with a partner, ensure you are spending enough time after cases to deliver feedback.

For a case that takes around 30 – 40 minutes, spend at least 15 – 20 minutes for feedback. Much of your learning and improvement will come from these feedback sessions.

Do not move onto the next step until you have done at least 5 – 10 cases and are beginning to feel comfortable with case interviews.

5. Practice with a former or current consultant

At this point, I highly recommend asking former or current consultants to give you a practice case. This will significantly help you prepare for case interviews.

Doing a mock case with a former or current consultant is highly advantageous because they know exactly how to run cases and give feedback. You’ll receive incredibly helpful feedback that your previous case partners likely missed.

If you feel that you are plateauing with your case partner, that is a sign you should do a mock case interview with a former or current consultant.

You can find former or current consultants among:

• People you met during the consulting recruiting process
• Your broader LinkedIn network

I would not ask a consultant that is involved with the consulting recruiting process for a case too prematurely. Although these practice cases are not evaluative, some firms will actually make note of how well you perform during the practice case.

At this point, you will have accumulated a long list of improvement areas from all of the different people you have cased with.

6. Work on your improvement areas

In this step of preparing for Deloitte case interviews, you will work on strengthening and fine-tuning your improvement areas. Examples of common improvement areas include:

• Creating a more complete and mutually exclusive framework
• Performing math calculations quicker or more smoothly
• Providing more structure to your qualitative answers
• Leading the case more proactively
• Delivering a more succinct recommendation

Try to focus on improving one thing at a time. This is much more effective than trying to improve everything at once.

For some areas, such as math, it will be better to work independently. For other areas, such as learning to proactively lead the case, it will be better to work with a case partner.

If you are looking for more cases, look at the resources listed in step four. If you are looking for specific drills or practice problems for a particular part of a case interview, check out The Ultimate Case Interview Workbook .

Do not move onto the next step until you have finished working on all of your improvement areas.

7. Stay sharp

If you have progressed this far, congratulations! You have almost finished preparing for Deloitte case interviews.

Once you feel that you have no more improvement areas to work on, the key is to not burn yourself out by doing too many unnecessary cases.

While each case that you do makes you slightly better, there is a point when doing too many cases can create case fatigue right before your interview. Case fatigue can negatively impact your interview performance.

On the other hand, you also don’t want to go weeks without having done a case. You may end up forgetting strategies or become rusty and slow.

Once you have achieved case mastery, I recommend doing no more than 2 cases per week in the weeks leading up to your interview. This ensures that you remain sharp for case interviews, but don’t have case fatigue.

How to Solve the Deloitte Group Case Interview

Deloitte is one of the few consulting firms that uses group case interviews in their final round of interviews. They conduct group case interviews because Deloitte’s work culture has a huge emphasis on teamwork and culture fit.

Here’s what to expect:

• You’ll be put into a group with 3 to 5 other candidates
• The interviewer will hand out case materials
• You’ll be given 10 minutes to review the case materials and prepare
• The group will have a discussion for 20 minutes
• During this discussion, interviewers will be observing candidates and will not interfere
• Afterwards, the interviewer will ask the group specific questions for another 20 minutes

Group case interviews can be challenging to prepare for because it is difficult to replicate the exact conditions to practice them. However, if you prepare for case interviews well, you will be in a great position to succeed in group case interviews.

Your goal in a group case interview is to add value to the group. There are six different ways that you can add value:

• Lead or facilitate the discussion : You can propose what topics to discuss, the order they should be discussed in, and how much time should be allocated towards each topic. If the group gets off track, you can bring the group’s focus back together.
• Expand upon other people’s ideas : If a group member suggests a great idea or raises a good point, build upon it and make it even better.
• Synthesize information : You can summarize information that other people have said and reconcile different viewpoints and ideas together.
• Keep track of time : You can volunteer to keep track of time and make sure that the group is on track.
• Play devil’s advocate : You can help your group develop strong ideas by testing the team’s thinking by considering potential risks or downsides of their ideas.
• Take notes:  You can keep track of what other people are saying so that you can recall what has been discussed if any group members have questions.

Follow these five tips to shine during your Deloitte group case interview.

Tip #1: Treat your group members as teammates, not competition

The group case interview is not an exercise in which you are competing with others. Interviewers are trying to assess whether you would be a great teammate. Multiple people or even all people in your group can receive job offers.

Therefore, focus on adding value to the group rather than making yourself look better than your teammates.

Tip #2: Don’t speak too much, but don’t speak too little

If you speak too much, this may be seen as being too aggressive or controlling. If you speak too little, you may come off as shy or timid.

If you were to rank all of the members in your group by how much each person spoke, you would want to be roughly in the middle. This would be the perfect balance of speaking and listening.

Tip #3: Don’t interrupt or talk over your group members

Interrupting others when they are speaking is rude and disrespectful. You do not want to be inconsiderate or a jerk. Be nice and respectful to your group members.

Tip #4: Involve other people

If you observe that someone has not spoken much, ask them for their thoughts or opinions. If you notice that someone has been cut off when they were speaking, ask them to finish their thoughts after the person interrupting them has finished what they have to say.

These are easy ways to show interviewers that you are a considerate and helpful teammate.

Tip #5: Speak only if you are adding value to the group

Just because you are speaking a lot during the group case interview does not mean that you are doing well. Interviewers are not assessing you purely on the quantity of what you say. They care more about the quality.

Great teammates know when to speak and when to listen. Therefore, you should speak only if you are adding some kind of value to the group. Interviewers can tell when people are speaking for the sake of getting air time.

Deloitte Behavioral and Fit Interview Questions

In addition to case interviews, you will likely be asked a few behavioral or fit interview questions. There are ten questions that are most commonly asked.

1. Why Deloitte?

How to answer: Provide your three biggest reasons why you’re interested in working at Deloitte. You could mention that you loved the people that you have met from Deloitte so far. You can talk about Deloitte’s massive global presence, their expertise in nearly any industry or function, or their professional development opportunities.

2. Why consulting?

How to answer: Again, provide three reasons for why you’re interested in consulting. You could mention the fast career progression opportunities, the learning opportunities to develop soft and hard skills, or the level of impact that you can make right away in consulting.

3. Walk me through your resume.

How to answer: Provide a concise summary of your work experience, starting with the most recent. Focus on emphasizing your most impressive and unique accomplishments. At the end, tie your experiences to why you are interested in consulting and why you would be a great fit for Deloitte.

4. What accomplishment are you most proud of? 

How to answer: Choose your most impressive, unique, or memorable accomplishment. Structure your answer by providing information on the situation, the task, the actions you took, and the results of your work. Explain why the accomplishment is so meaningful to you and what qualities that reveals about you as a person.

5. Tell me about something that is not on your resume.

How to answer: This is a great opportunity to highlight an accomplishment that is not related to your professional work experience. Perhaps there is a non-profit that you volunteer at, a side project or business that you work on, or a hobby that you have won awards or recognition for. Select an accomplishment that is impressive and interesting.

6. Tell me about a time when you had to lead a team.

How to answer: If possible, choose a time when you directly managed a person or a team. For this question and the following similar questions, make sure that you structure your answer. Provide information on the situation, the task, the actions you took, and the results of your work. This is known as the STAR method and is the most common way of answering behavioral or fit interview questions. 

7. Describe a time when you faced conflict or disagreement.

How to answer: When answering this question, focus on emphasizing the steps you took to resolve the conflict or disagreement. Speak about the interpersonal skills you had to use in order to mediate the situation. Interviewers want to know that you can handle conflict in a constructive way.

8. Give an example of a time when you successfully persuaded someone.

How to answer: Choose a time when you were able to change someone’s mind who originally disagreed with you. Focus on emphasizing the steps that you took to persuade that person and what impact this had on the organization. Interviewers want to know that you are a great communicator and have strong people skills.

9. Tell me about a time when you failed.

How to answer: Choose a time when you failed to meet a deadline or did not meet expectations. You do not want to pick a failure that is too big or embarrassing. Focus on emphasizing what you learned from the experience and how you used that experience to deliver even better results in the next opportunity that you got. Interviewers want to see that you strive to learn from your past failures and are always working to get better.

10. Are there any questions that you have for me?

How to answer: This is a fantastic opportunity to get to know the interviewer on a more personal level. Ask them questions about their experience in consulting. Ask what their favorite case was or what they are looking to do next in their career. The more you can get the interviewer talking about themself, the more likely they will be to have a positive impression of you. People love talking about themselves, so make sure to listen attentively and ask follow-up questions.

If you do decide to eventually use a case interview coach, consider using our case coaching service .

There is a wide range of quality among coaches, so ensure that you are working with someone that is invested in your development and success. If possible, ask for reviews from previous candidates that your coach has worked with.

Understanding the Deloitte management consulting case interview structure

The Deloitte case interview usually lasts for about an hour and has two parts. The first part typically includes questions about your resume, your background, your interests, and your experiences. The second part of the interview includes case questions, which are designed to test your problem-solving skills, analytical abilities, and communication skills.The case typically presents a business problem that requires a solution, and you'll be expected to come up with a strategic plan to solve it. The interviewer will assess your ability to gather and analyze information, develop a hypothesis, identify critical issues, and communicate your ideas effectively. You may need to use math, charts, and visuals to support your analysis and recommendations.

In addition to the case questions, Deloitte may also include behavioral questions in the interview. These questions are designed to assess your personality, work style, and ability to work in a team. You may be asked to describe a time when you faced a difficult situation at work and how you handled it, or to give an example of a time when you had to work with a difficult team member.It's important to prepare for the Deloitte case interview by practicing with sample cases and behavioral questions. You should also research the company and its culture, as well as the industry and market trends. This will help you to demonstrate your knowledge and understanding of the business world, and to show that you are a good fit for Deloitte's consulting team.

Essential tips for acing your Deloitte case interview

To ace your Deloitte case interview, follow these essential tips:

• Practice, practice, practice: Practice with as many case questions as possible, read case studies, and engage in mock interviews with friends, family, or advisors.
• Be clear and concise: Use clear and concise language, avoid jargon, and explain your ideas in a structured and logical way.
• Be creative: Think outside the box and develop innovative solutions that differentiate you from others.
• Be curious: Ask insightful and relevant questions to clarify the problem, gather more information, and show your interest.
• Be confident: Believe in your abilities, speak clearly and confidently, and maintain eye contact.

During your Deloitte case interview, you can expect to encounter scenarios such as:

• An operational challenge arising, such as a supply chain disruption or a product quality issue, and you're asked to diagnose the problem and propose solutions.
• A merger or acquisition taking place, and you're asked to assess its financial and strategic implications, and suggest recommendations.

Additionally, during the Deloitte case interview, you may also be asked to analyze a company's financial statements and identify areas for improvement or growth. You may also be presented with a hypothetical scenario where a client is considering a major business decision, and you're asked to provide a recommendation based on the available information.

How to research and prepare for a Deloitte case interview

To prepare for your Deloitte case interview, you need to:

• Research the company: Understand Deloitte's business model, its services, its clients, its culture, and its values.

• Build your knowledge: Read business books, attend business conferences, and engage in case discussions with professionals to build your business acumen.
• Practice with case questions: Solve practice cases, read case studies, and engage in mock interviews with experts.

Additionally, it is important to understand the different types of case interviews that Deloitte may conduct. These can include market sizing cases, profitability cases, and business strategy cases. It is important to practice and prepare for each type of case to ensure you are fully prepared for any scenario. It may also be helpful to seek guidance from current or former Deloitte employees to gain insight into their interview experiences and tips for success.

• Recommend solutions: Develop actionable and creative recommendations that address the root cause of the problem and are aligned with the constraints of the case.

Sample questions and scenarios you might encounter during a Deloitte case interview

• If you were the CEO of a retail pharmacy chain, what would you do to improve the profitability of your operations?
• How would you structure a feasibility study to determine whether a leading e-commerce company should enter the luxury fashion market?
• If a manufacturing company is experiencing declining sales, what are the key questions you would ask to identify the root cause?

Common mistakes to avoid during a Deloitte management consulting case interview

To avoid common mistakes during your Deloitte case interview, avoid:

• Jumping to conclusions without analyzing the data thoroughly.
• Being too rigid in your analysis and not adjusting your approach when needed.
• Not clearly articulating your thought process or hypothesis.
• Being overly confident or aggressive in your communication style.
• Not asking relevant questions to clarify the problem or gather more information.
• Being too focused on finding the "right" answer instead of demonstrating your problem-solving skills and reasoning.

• Use humor or storytelling to break the tension, engage the interviewer and demonstrate your personality.

• Spend time researching the latest trends in the industry, and get comfortable with market analyses and other types of data.
• Practice interviewing with other consultants or former interviewees, and ask for constructive feedback about your approach and delivery.

The Deloitte Case Interview: What to Expect

Deloitte Group Case Interview

Have an interview with Deloitte Consulting coming up? If so, you’ll want to know what to expect and how to prepare.

We’ve got you covered, including our 6 tips on how to ace your Deloitte case interview!

In this article, we’ll discuss:

• What the Deloitte Consulting case interview process looks like,
• The Deloitte case interview: what to expect,
• Sample Deloitte case interviews,
• Our 6 tips on acing the Deloitte case interview,
• The Deloitte group case interview, and
• The Deloitte behavioral interview question.

Let’s get started!

What the Deloitte Consulting Interview Process Looks Like

Initial application.

The Deloitte Consulting interview process has 4 steps:

• Application
• Online assessment
• First round interviews
• Final round interviews

If you’re a student, make sure you know if you need to apply directly to Deloitte Consulting or through your career center.

As part of your application, you’ll need to submit your resume and, for campus hires, your academic transcript. Research which office you want to apply for as you’ll need to state that at this stage.

Nail the case & fit interview with strategies from former MBB Interviewers that have helped 89.6% of our clients pass the case interview.

Deloitte Online Assessment

The second stage of the Deloitte Consulting recruitment process is an online assessment. This assessment tests numerical reasoning and your situational judgment.

Information from recent candidates suggests there are 35 questions split over 5 distinct sections. We’ve got all you need to know about this part of the process in our article, Deloitte Online Assessment: What It Is & How To Pass .

Deloitte Consulting First Round Interviews

If you’re selected for a Deloitte interview you’ll be contacted via your campus career center or direct by the Deloitte recruiting team.

For campus hires, first-round interviews often take place on campus and include one or 2 interviews. These interviews include both case and behavioral interview questions. We’ve heard the cases include market-sizing as well as the non-profit sector.

The same types of interviews are used for non-campus hires.

Deloitte Consulting Final Round Interviews

Final round interviews may take place virtually, on campus, or in a Deloitte office. While the exact format depends on the position you’re applying to, expect both behavioral and case interviews at this stage. Candidates may also have a group case interview.

Deloitte will let you know the outcome of your application within a week of the final round interview.

Case interviews can feel daunting for many candidates. In this section, we’ll cover what type of cases Deloitte uses and how to approach them so you can feel confident in tackling them.

What Exactly Is a Case Interview?

A case interview is an interview conducted within a business context.

The interviewer will present information about a company and a business problem it faces. These 2 elements together are known as a case.

Case interviews can either be candidate-led or interviewer-led depending on who is expected to steer the order in which different aspects of the case are analyzed.

Deloitte case interviews are predominantly candidate-led which means they’ll be looking to you to take control of solving the case — breaking down the problem, choosing a suitable business framework, and asking for appropriate data to fill in the gaps.

What Type Of Cases Does Deloitte Consulting Use?

The branch of Deloitte Consulting you are applying for can influence the business context you receive in the case. There are 3 parts to Deloitte Consulting:

• Strategy and Operations (S&O) focuses on corporate issues such as organizational strategy, supply-chain improvement, operating model transformation, and business process improvements.
• Technology Consulting focuses on technology issues such as digital strategy, IT program delivery, infrastructure and software solutions, and cybersecurity.
• Human Capital focuses on people issues such as organizational transformation, cultural change, knowledge management, and talent acquisition and development.

So, if you were applying for a Human Capital role you might get an organizational transformation case or, if you were applying to S&O you might get an organizational strategy case

Whichever branch you’re applying to, there are going to be certain skills Deloitte Consulting is looking to test through the case interview process.

What Skills Is Deloitte Consulting Looking to Assess?

Deloitte uses case interviews as a way to assess skills it values in its consultants.

• Structured problem solving
• Analytic skills
• A balance of creativity and practicality

Structured Problem Solving

The ability to carefully think through a problem in a structured and logical way, is a key skillset for consultants. You’ll need to be able to break down a business problem to identify and analyze root causes and potential solutions.

Case interviews test this skill by providing lots of data for you to manage within an unfamiliar business context. Your ability to sort through information to pull out what’s most relevant to the issue will be assessed.

Analytic Skills

Deloitte Consulting will assess your numerical ability during the case interview. Make sure you brush up on your math skills in advance of the interview. Our article on Case Math tells you what to expect.

A Balance of Creativity and Practicality

Case interviews give Deloitte recruiters a chance to see how creative you are when searching for an answer to a thorny problem. Clients hire consultants to solve complex, multi-factor problems, not for mundane issues they can solve themselves.

However, innovative thinking needs to be balanced with good business sense. Suggesting solutions that aren’t viable or attractive to the client shows you lack practical business judgment.

Whatever your recommendation, make sure you highlight the risks associated with it and how those could be managed.

Case interviews can feel challenging — very like tackling a real-life client problem! They’re the perfect environment for interviewers to see how comfortable you are with ambiguity and how resilient you are when things get tough.

Whether that’s grappling with a tricky calculation, or struggling to see how the pieces fit together, make sure you don’t give up. Take a breath and give yourself a moment to clear your head. Then jump back in and keep going.

How Do I Tackle a Deloitte Consulting Case Interview?

There are 4 key stages to tackling any case interview:

• Opening . Make sure you fully understand the client’s problem. Repeat back to the interviewer your understanding of the issue so they have a chance to guide you if you’ve misunderstood. Ask any clarification questions you need.
• Structure . Brainstorm all the issues or factors related to the client’s problem that need to be considered. Be explicit about any underlying assumptions you are making to check their accuracy with your interviewer. Organize your thoughts into a logical sequence to make sure you tackle all of them in your analysis.
• Analysis . Gather and review all the data available to you. Data can be communicated directly by your interviewer or come in the form of exhibit. Complete any calculations required. Identify the most important issues and use this to formulate a recommendation.
• Conclusion . Present your findings to the interviewer and give your final recommendation. State any risks associated with the recommendation and how you’d mitigate them. Outline the next steps and the expected result of taking them.

For more information on using these 4 steps to tackle case interviews see Our Ultimate Guide to Case Interview Prep .

Once you’ve got the 4 stages nailed, it’s time to practice! Doing the thinking is only half the battle in a case interview, you’ve also got to effectively communicate your thoughts.

Practicing with friends, people in your network who are also going through the process, or with former consultants who can coach you through it, is critical to your confidence and success.

Links to Sample Deloitte Case Interviews

You can find links to several Deloitte case interviews in our Case Interview Examples article, as well as dozens of cases from other major consulting firms. The Footloose example has a lot of data exhibits so it’s a good one for practicing how to effectively manage information.

In addition, Deloitte has a very helpful tool on their site that helps you practice case interviews. Each of these cases is 15–20 minutes long and presents you with a real-life business problem and a number of questions.

You can prepare your answers to these cases then compare your thoughts to the Deloitte model answers provided.

Our 6 Tips on Acing the Deloitte Case Interview

Tip 1: keep organized notes.

Deloitte case interviews can last up to an hour and have a lot of information to review. Make sure you take organized notes throughout so you don’t forget anything important or miss something in your analysis.

Neat and logical notes also show you can manage large amounts of data effectively.

Tip 2: Ask Questions to Fill In the Gaps

It’s important to fully understand the problem you’re trying to solve. Don’t be afraid to ask clarification questions or for more data to fill in any gaps in your analysis. Asking questions gives the interviewer insight into how you’re approaching the problem.

Tip 3: Take Time to Organize Your Thoughts

Make sure you take your time during the interview to compose yourself and structure your thoughts. It’s tempting to launch into responding straight away but give yourself space to think through your answer first to make sure you don’t miss something or forget an important point.

Tip 4: Utilize a Framework and Develop a Hypothesis

Using a business framework or an issue tree helps you drill down into the heart of the problem. This means you’re more likely to develop a hypothesis that solves the key issue the client is facing.

Keep referring back to your issue tree and hypothesis during your Deloitte interview to make sure your analysis is logical and hasn’t gone down a rabbit hole!

Tip 5: Structure Your Recommendation

Present your analysis in a clear and structured way. Start with the main takeaway — your recommendation. Then walk your Deloitte interviewer through your analysis in a logical way, highlighting the most important points and explaining how they led you to draw the conclusion you have.

Share any assumptions you’ve made to reach your recommendation and also any associated risks. This shows you’ve thought more broadly about the problem in the context of the business as a whole.

Tip 6: Don’t Forget to Breathe!

While case interviews can feel daunting, try not to panic. Viewing the case as a business conversation that showcases your ability to think through a problem, rather than as something that must be solved, can ease the pressure.

As part of the final round assessment, Deloitte Consulting uses group case interviews.

As many of the top consulting firms don’t use group case interviews, candidates can be unsure of what to expect. But, don’t worry, we’ve got you covered!

What Happens In the Deloitte Group Case Interview

In Deloitte group case interviews you’ll be organized into a group with 3-6 other candidates. The group will be presented with information about a case that they’ll need to work together to solve.

• For the first 10 minutes, you’ll work alone, or in a pair, to review the information and prepare your thoughts.
• The group will then discuss the problem for 20 minutes, sharing analysis, and preparing a recommendation for the client. During this discussion, interviewers will observe the group to see how you interact with each other.
• For the final 20 minutes, interviewers will ask questions of the group.

Our Top Tips for the Deloitte Group Interview

Group case interviews are your opportunity to stand out against other candidates. Interviewers will be observing the group dynamics and looking for great communication skills, strong analysis, and leadership.

Here are our top tips:

• Add value with your contribution . Everyone knows interviewers are looking for participation but it’s not enough just to speak up during the group case interview — what you say matters. Your contribution should add fresh insights to what’s already been said. This shows good listening and analysis skills.
• Showcase your leadership ability . Leadership isn’t just about speaking first or dominating the conversation. Facilitate the conversation and bring other team members into the discussion if they haven’t had a chance to speak. This shows you value the contribution of others, which links to one of Deloitte’s core values: foster inclusion . Do be proactive about proposing points for discussion, managing time, and bringing the group back on track if you lose focus.
• Recognize others as teammates . While demonstrating leadership is important, it’s equally important to remember you’re trying to deliver value to the client. Make contributions that bring the group closer to a recommendation — don’t sidetrack the discussion just to stand out. Acknowledge the great ideas of others — which shows confidence — and then add to them.
• Summarize the discussion . At the end of the group discussion, summarize the main points of the conversation and state the group’s recommendation. You can also do this throughout the interview, any time when a lot of points have been discussed and a quick recap would be helpful.

This is important as it shows good communication skills and the ability to synthesize large amounts of data. It also makes sure that everyone’s on the same page and clear about the next steps, which is critical when dealing with real-life clients.

Deloitte Consulting Behavioral Interview Question

The Deloitte behavioral interview has 2 types of questions: fit questions and personal experience questions.

Fit questions help interviewers judge whether you’d fit into the Deloitte culture. Personal experience questions help them judge whether your skills and personal qualities match those they’re looking for in a consultant.

Top 3 Fit Questions and How To Ace Them

1. Why Do You Want To Work For Deloitte Consulting?

This is the top fit question and for good reason. Deloitte Consulting cares about recruiting people who really want to work there and value its specific culture and approach. 

Consulting firms invest heavily in developing their new recruits and they need you to stay long enough to make that investment worth it. So they’re expecting you to join the firm with eyes wide open.

Tackle this question by having a few good reasons why Deloitte is the company for you. The best answers are personal to you. 

Maybe you’ve been inspired by someone you’ve met from the firm. Or there’s something about Deloitte core values that really matters to you. That’s what recruiters want to hear about.

Deloitte Consulting’s core values are:

• Lead the way
• Serve with integrity
• Take care of each other
• Foster inclusion
• Collaborate for measurable impact

2. Why Consulting?

Consulting can be intense, so consulting firms are genuinely concerned that you understand what’s required of you and have the potential to meet the challenge. This question is your chance to explain why consulting is the career for you.

Whether that’s because you get to work with senior management early in your career or you’re excited about the opportunity to make a difference, make sure you’re clear on your motivation.

3. Tell Me Something About You That’s Not On Your Resume.

It’s easy to curate a polished, professional profile on paper. But interviewers are interested in who you are outside of work too.

This question provides an opportunity for you to talk about something you’re passionate about, and show a more human side. Bear in mind the Deloitte Consulting core values when you’re considering how you’d tackle this question.

For example, maybe you organize a community garden to provide food to local families. Or you spend time as a reading volunteer at your local care home.

Contributions you make as a volunteer can demonstrate your leadership capability as well as other ways you create a positive impact in your daily life.

Personal Experience Questions And How to Approach Them

A typical personal experience question starts with “Tell me about a time when…”

They help the interviewer see how your experience has helped you build the skills that make you suitable for consulting.

Examples include:

• Tell me about a time you disagreed with someone and how you worked through the problem.
• Tell me about a time when you led a team to solve a problem.
• Give me an example of when you had to deal with adversity. How did you resolve it?
• Tell me about a time when you changed someone’s mind on an important topic.
• How did you go about deciding on your class project recommendation?

The best approach to tackling a personal experience question is to tell stories. Stories are engaging and stick in the interviewer’s mind even after a long day.

However, like everything else in the case interview, your answer should be well-thought-through and structured. Don’t just launch into your story without thinking.

We recommend using the A STAR(E) framework to make sure your story is impactful and covers all the main points.

Using the A STAR(E) Framework

The A STAR(E) framework covers the following points:

• Answer . Start with a clear, short answer to the question.
• Situation . Give your story some context. Who were the people involved in the story? When and where did it take place?
• Tension . What was the problem you faced? The conflict or challenge?
• Action . What action did you take to resolve the issue?
• Result . What happened as a result of your action?
• Effect . What did you learn?

The (E) is in parentheses because this won’t be relevant to every story.

Remember the behavioral interview is also an important opportunity to learn more about Deloitte so you can feel confident you’re making the right choice.

In fact, that’s one of 6 key things Deloitte Consulting encourages candidates to bear in mind when tackling the behavioral interview:

• Share personal experiences to illustrate your critical skills and achievements.
• Describe experiences and career/life periods reflected in your resume.
• Focus on the positives of all your past experiences and remain optimistic.
• Use this discussion to learn more about Deloitte Consulting.
• Relax, be yourself, and help us get to know you.
• Use your time wisely; it’s your time, make sure you get your points across.

This article on performance management was originally published on business.com .

Deloitte is the largest professional services network in the world in both revenue and number of professionals. In 2013–14, they earned a record of $34.2 billion USD in revenue. So, when one of the biggest companies in the world takes on reinventing performance management, they do it with a bang.

Marcus Buckingham and Ashley Goodall described the process and findings of the large-scale Deloitte  performance management survey in the Harvard Business Review . We also examine how Deloitte changed their approach to performance management. In addition, we review the practical takeaways from Deloitte’s case study. The goal is to reexamine our own performance management system and how we can change it.

Old vs. new approach to performance management

Deloitte found that their current approach to performance management, annual 360 feedback, was wasting a shocking 2 million hours per year. Even more significant, they realized that their system wasn’t engaging employees at all. Performance levels were also dropping drastically. In an effort to combat this, Deloitte built something much more nimble, real-time, and individualized. They wanted something that was focused on fueling performance in the present rather than assessing it in the past.

First, let’s look at how Deloitte needed to change. You will find some of your own problems there. You should identify any issues. This is the first step to towards a useful solution.

With 360 feedback, goals were set once a year and reviewed once a year. The problem with this approach is that annual goals are too “batched” for real-time situations and a lot of time is wasted on performance ratings. Instead, this time should be spent on talking to people about their performance and careers consistently.

[Tweet “Insight: “Shift your performance evaluation focus from the past to the future””]

Their next realization was that assessing someone’s skills is always subjective.  The process says much more about the evaluator instead of the person being evaluated. This is called an idiosyncratic rater effect.

The discovery left Deloitte puzzled. They knew that in order to get the best feedback, it needs to come from a team leader. But how do you deal with the idiosyncratic rater effect?

[Tweet “Insight: “Ratings reveal more about the rater than they do about the ratee.””]

Before deciding how to deal with biased assessments, let’s take a look at another insight Deloitte discovered. They used the Gallup 1.4 million employee study to see what the similarities are between high and low performing teams .

The most powerful characteristic was that the high-performing team members felt they were doing their best to accomplish meaningful goals. On that basis, Deloitte identified 60 high-performing teams from their own ranks. Using these teams, they conducted a six-item survey to find out what their own high-performing teams had in common.

Insight: The most powerful commonality between Deloitte’s highest performing teams was the belief that “I have the chance to use my strengths every day.”

When the results came back, the most common trend was that their own high performing team members felt that they had the chance to use their strengths every day.

So, what can we learn from these results?

Deloitte set out a clear goal: “We want to spend more time helping people use their strengths.”

So, for a quick recap: Deloitte was able to recognize the strengths in performance. The concern came with evaluating it. They also now knew that the best insight comes from the immediate team leader, but how can they do provide it without the idiosyncratic effect getting in the way? That’s the million (or even a billion) dollar question.

Insight: “The key is that people rate other people skills inconsistently, but they are highly consistent when rating their own”

We also know that everyone rates other peoples’ skills inconsistently. To combat thisDeloitte did not ask team members what they think of each team member. Instead, they asked team leaders to rate their own future actions regarding each team member.

Here are the statements Deloitte asked leaders to select about an employee in order to overcome the idiosyncratic effect:

• Given what I know of this person’s performance, and if it were my money, I would award this person the highest possible compensation increase and bonus – this measures overall performance and unique value.
• Given what I know of this person’s performance, I would always want him or her on my team – this measures ability to work well with others
• This person is at risk for low performance – this identifies problems that might harm the customer or the team on a yes-or-no basis
• This person is ready for promotion today – this measures potential on a yes-or-no basis

[Tweet “Insight: In effect, they are asking what the team leaders would do, not what they think.”]

This evaluation is called “process performance snapshot.” The big difference is that it evaluates performance in real-time. Now they had the system to measure the performance. The question next became – how can we improve it?

Suggestions to reinvent performance management

One factor stood out the most from Deloitte case study – frequency. Deloitte points out that the optimal frequency of these new performance reviews should be weekly . They also suggest that the best way to ensure frequency is to have regular check-ins about near-time work initiated by team members.

Deloitte performance is also getting impact from a consumer technology platform that is designed to be simple, quick and above all, engaging. People tend to be interested in themselves – their own insights, achievements, and impact, so they believe that employing such a method would engage an employee around their own performance in a way they had not done before.

We’ve sorted the reviewing, so what about the reviews? Most team members are rated on a single number, but Deloitte began to wonder if that was the easiest way of viewing personal performance.

Deloitte hasn’t found the answer yet. From our perspective, team members should get a weekly progress report where there are 4 different indicators that correlate into the weekly score. The weekly score takes into account the individual’s happiness, progress, overdue Plans, and Problems. We don’t know if this is what Deloitte might be looking for, but it is definitely a step forward in the right direction.

To conclude, Deloitte realized that traditional, once-a-year, 360-reviews were inefficient. They also do not give a transparent view of the current working situation. It is time to reinvent the performance management process . Ask your team leaders to assess their team members through statements that describe what they do, not what they think.

Employee performance snapshots should be regular and weekly. The technology should be designed to be simple, quick, and above all, engaging to use.

Deloitte Case Interview (questions, process, prep)

Deloitte interviews are pretty challenging compared to regular interviews at large companies. The questions are difficult and the interview format is specific to Deloitte.

But the good news is that with the right preparation it can actually become relatively straightforward to succeed at a Deloitte interview. We've put together this ultimate guide to maximise your chances of success.

Here's an overview of what we'll cover.

• Introduction to Deloitte
• Interview process
• Regular case interviews
• Group case interviews
• Fit and PEI questions
• Preparation plan

1. deloitte consulting is bigger than mckinsey + bcg.

Deloitte is a force to reckon with in consulting. In 2022, it generated ~$26bn in revenue from its consulting business line. This makes it about as big as McKinsey, Bain and BCG combined.

Deloitte Consulting grew through a series of acquisitions. As a result, it's a collection of relatively independent firms operating under the Deloitte Consulting umbrella. Each member firm is managed by local partners who are responsible for their P&L. This is why you get more variation across different offices and regions than you do at a firm such as McKinsey.

Deloitte Consulting has three main practice groups you need to be aware of when applying:

1. Strategy and Operations (S&O) focuses on topics such as corporate strategy, supply-chain improvement, business model transformation, process improvements, etc.

2. Technology consulting focuses on digital strategy, delivery of IT programmes, cyber risks management, designing and building tech-based solutions for clients, etc.

3. Human capital focuses on topics such as organisation transformation, change management, corporate learning and development, diversity and inclusion, etc.

In 2013, Deloitte acquired Monitor which was initially founded by Michael Porter, the father of Porter's five forces . Monitor is now part of Deloitte S&O and that brand is particularly strong in North America.

The type of work Deloitte S&O does is very similar to what you would do at McKinsey , BCG or Bain . If you'd like to learn more about how Deloitte (and the other Big 4 firms) compares to the MBB firms, check out our MBB vs. Big 4 guide . 

2. Deloitte interview process

Your interview process with Deloitte will depend on whether you're applying as an experienced or early career candidate. There is also some variation by country, so we recommend that you ask your local HR contact at Deloitte for more details.

Below is an outline of the most common interview process and will be correct for the majority of candidates.

2.1 Early career candidates 

As an early career candidate you can apply online. You'll need your educational qualifications to hand, and you'll need to meet the minimum requirements.

The next step is an "immersive online assessment". Here you'll be asked to look at work scenarios and answer how you would respond.

Once you've completed it, you'll receive a "bespoke feedback report about your strengths and abilities".

If you fail the assessment, you'll hear back within a couple of days, but if you pass it may take a week or two before Deloitte contacts you - so in this case, no news is good news!

If you pass, you'll go onto the next assessment step: the "job simulation". You’ll answer questions across formats that include writing, video, multiple choice and ranking. Make sure you're dressed correctly and are in a quiet place before starting the simulation.

After you’ve completed the simulation, you'll get an email letting you know how you did within four weeks.

If successful you would then have a "Final stage assessment", which is a video interview with a senior consultant or an online group exercise. This would be the last step in your interview process.

2.2 Non-early career candidates

If you're an experienced candidate, or at least not an undergraduate or recent graduate, the interview process will probably consist of three steps:

• Resume and cover letter screening
• First round interviews
• Second round interviews

2.2.1 Resume and cover letter screening

First, recruiters will look at your resume and assess if your experience matches the open position. This is the most competitive step in the process—we’ve found that 90% of candidates don’t make it past this stage.

You can use  this free resume guide  and this  free cover letter guide  to help tailor your application to the position you’re targeting. 

And if you’re looking for expert feedback, you can also get input from our  team of  ex-MBB recruiters , who will  cover what achievements to focus on (or ignore), how to fine tune your bullet points, and more.

2.2.2 First round interviews

Your interviewers at Deloitte will consist of a mix of senior consultants, managers and partners. First round interviews may be done in person or via video or phone call. They usually consist of:

• one behavioural interview (30 to 45mins)
• one or two case interviews (30 to 45mins each).

This is quite similar to what you could expect at other consulting firms.

2.2.3 Second round interviews

Second round interviews are similar to first round interviews, though the line of questioning can be a bit tougher. Your final interview is usually with a hiring partner, and before that you may face a group case interview.

• One behavioral interview (30 to 45mins)
• One case interview (30 to 45mins)
• One group case interview (45mins - 1hr)

Now you've seen an overview of the interview process, let's take a detailed look at regular case interviews and group case interviews at Deloitte, and how you should prepare for them.

3. Deloitte case interview questions

Case interviews at Deloitte are candidate-led. The style is therefore similar to what you will experience in a BCG case interview or a Bain case interview . Our research and experience tells us that there 7 types of questions you need to prepare for in candidate-led case interviews:

• Framework development
• Framework exploration
• Quant question – Data provided
• Quant question – No data provided
• Creativity question
• Recommendation

You can learn more about case interviews and how to prepare in our free case interview guide . One unique thing about Deloitte case interviews is that they will occasionally (but not always) give candidates written materials and a few minutes to review before they start the interview. This type of scenario requires the kind of skills you could learn in our free written case interview guide .

Deloitte has produced some very useful material to help candidates prepare. Take a good look through this practice case .

Deloitte has also shared some example case studies that you can work through interactively:

• Deloitte case study 1: Federal health agency needs to respond to Ebola epidemic (Advanced)
• Deloitte case study 2: Talent management for the Civil Cargo Protection Bureau (Advanced)
• Deloitte case study 3: Engagement strategy for a huge federal agency (Undergraduate)
• Deloitte case study 4: Recreation Unlimited, a global apparel and sportswear company, must reverse declining market share (Undergraduate)
• Deloitte case study 5: Federal benefits provider needs to formulate its 10-year vision (Undergraduate)

All these strategy cases can all be found on Deloitte's case interview prep tool, along with some Application Program Analyst cases and Business Technology Solution cases.

4. Deloitte group case interview

As mentioned above, Deloitte also uses group case interviews in its final round. Here is the key information you need to be aware of for this interview format:

• Candidates get divided into groups of 4 to 6
• Each group is given information about a case (i.e. a client facing a problem)
• You are given 10mins to review the materials by yourself or with another person in your group
• You are then asked to discuss a few questions about the case for 20mins with the rest of your group in front of your interviewers
• The interviewers will ask a few questions to the group for 15 to 20mins

This type of case mainly tests your ability to work with others. Interviewers won't intervene during the group discussion. They will just observe the group dynamics and mark each participant based on how they are contributing to the discussion.

Here are the top 3 things you should aim to do in your Deloitte group interview:

• Speak with a purpose. At the beginning of a group discussion, a lot of candidates will want to speak their mind as they know participating is important. But participating is not enough. The QUALITY of your input is crucial. Sometimes, it's better to let two or three people get the discussion started. And to then make a very thoughtful point based on how they started the discussion. Focus on the quality of your input, not the quantity.
• Involve everyone. Another tip that's easy to apply is to keep an eye on who's participating in the conversation and who's not. If you identify a member of the group who's struggling to make themselves heard, you should not hesitate to help them be heard by saying something like: "We haven't heard everyone's opinion on this yet. John, Rebecca what do you think?"
• Summarise. Finally, at the end of the 20 minutes group discussion it's a good idea to summarise the different points people have made. This will position you as the person bringing everyone together and making sure all candidates are on the same page. It is something some partners in consulting like doing with clients in real life and will therefore reflect positively on you.

And the top 3 things you should really avoid doing :

• Looking nervous. Group interviews is the time to put your poker face on. Everyone is stressed in a group interview. But you need to try your best to come across as confident. A good way to do this is to focus on basic body language: look at people in the eye, sit confidently, don't cross your arms, etc.
• Interrupting others. Consultants need to be client-friendly, and interrupting someone in a discussion is not client-friendly at all. You should listen carefully to what others are saying. Try to have a genuine interest in what they think. Before making your point, summarise their point to show that you understand what they mean.
• Dominating the conversation. Finally, some candidates are so eager to participate in the conversation that they end up completely dominating the rest of the group without realising it. A good tip to avoid this is to keep an eye on how much time you talk. If you are in a 5-person group you should aim to speak 20% (1/5th) of the time and really no more than 25%.

Your performance in regular and group case interviews will play a big role in Deloitte's decision to give you an offer. If you'd like to learn more how to approach group interviews, check-out our  separate detailed  guide to group case interviews.

5. Deloitte behavioral questions

Behavioural interview questions asked at Deloitte fall into two categories:

• Fit questions. These are generic questions such as “ Why consulting? ” or “ Why Deloitte? ”.
• Personal Experience Interview (PEI) questions. These are questions such as “Tell me about a time when you led a team through a difficult situation.” Or “Tell me about a time where you had to manage a team conflict”

Here are the top 5 fit and PEI questions you should prepare for at Deloitte and other consulting firms.

Top 5 fit questions:

• Why Deloitte?
• Why consulting?
• Walk me through your resume
• Tell me about something not on your resume
• Tell me about your greatest accomplishment

Top 5 PEI questions. Tell me about a time when ...

• You led a team through a difficult situation
• You worked in a team and had to manage a conflict
• You had a disagreement with a colleague / boss
• You had to change someone's / a group's mind
• You overcame a really difficult challenge

Don't fall into the trap of under-preparing for these types of questions. While they may seem easier than the case interviews, they are extremely important to get right.

You’ll need to prepare several ”stories” or “examples” from your personal and professional experience to demonstrate that you have the traits that Deloitte is looking for.

To learn more, check out our guide to consulting fit / PEI questions .

6. Deloitte case interview preparation plan

Now that you know what to expect in Deloitte interviews, let's discuss the steps you should take to prepare.

6.1 Learn the case interview essentials

The best starting point for your case interview prep is our case interview prep guide . It'll take you through all the different types of questions you may be asked in your case interview, show you how to draw from different frameworks to structure your answer, and give you example cases to practise with.

6.2 Become really confident at maths

You don't have to have a perfect GPA or GMAT score to succeed at case interview maths. However, during your Deloitte  interviews, you will be expected to quickly perform accurate mental maths. 

In order to do this, it’s essential to know the formulas for common metrics, like return on investment or breakeven point. And it’s also helpful to know a few maths shortcuts to help you solve problems more quickly. To learn more about these topics, check out our free guide to case interview maths . 

In our experience, the most successful applicants start their interview preparation by practising maths skills, so make sure you prioritise this step.

6.3 Research the company

Deloitte interviewers want to hire candidates who are deeply motivated to work for their firm. Make sure you're up to date in the latest developments in the area of the company you're applying to join. Here are some useful links to get you started:

• Deloitte's insights page
• Deloitte's selection of business podcasts
• Financial Times' news articles on Deloitte

In addition, do some networking so that you can show you've made the effort to reach out to current staff.

6.4 Do mock interviews

How you solve each case is important, but your interviewers will also be evaluating how you COMMUNICATE your answers. It's important to speak in a structured way that makes it easy to clearly understand your points.

The best way to hone your communication skills is to practise interviewing out loud, and you can do that in three main ways:

• Interview yourself (out loud)
• Practise interviewing with friends or family
• Practise interviewing with ex-interviewers

To help you with this process, here is a  broad  list   of consulting interview questions  you can practice with.  Practising by yourself is a great way to get started, and can help you get more comfortable with the flow of a case interview. However, this type of practice won’t prepare you for realistic interview conditions.

After getting some practice on your own, you should find someone who can do a mock interview with you, like a friend or family member.

We’d also recommend that you practise 1-1 with ex-interviewers from Deloitte . This is the best way to replicate the conditions of a real case interview, and to get feedback from someone who understands the process extremely well. Meet our Deloitte ex-interviewers who’d love to work with you.
