Deloitte Case Interview

Eyeing a career at Deloitte? You’ll have to ace the feared Deloitte case interview. What is Deloitte? Deloitte is one of the Big 4 firms with offerings spanning Tax, Audit, M&A, Risk, and Consulting. Out of all the Big 4 firms, Deloitte is generally considered to have the most prestigious consulting offering. The firm is one of the largest consulting firms by revenue globally and, as such, has significant volume and breadth of work. Unlike companies like McKinsey, Bain, and BCG whose consulting services historically focused on strategy, Deloitte’s offerings span:

Deloitte differentiates itself in its ability to serve clients holistically from strategy through operations while also transforming their clients’ workforces and enabling their clients’ underlying technology.

The Deloitte case interview is designed to mirror a real-world consulting project and is used to test the candidate’s problem solving and analytical skills. The cases are also designed to test business judgment and logic.

Generally, the Deloitte case interview follows similar structures to those from other consulting firms (e.g., BCG, Bain, Oliver Wyman). However, within the interview process, Deloitte typically includes one group interview which is less typical for other firms.

Let’s jump in.

Deloitte Case Interview

Table of Contents:

Keys to the deloitte case study interview, the deloitte recruiting process, core skills to showcase to deloitte, deloitte case interview framework, deloitte case interview questions, deloitte interview case study examples, deloitte group case interview, deloitte strategy and analytics consulting case interview, deloitte human capital consulting case interview, deloitte enterprise technology and performance consulting case interview, deloitte federal consulting case interview.

There are multiple keys to the Deloitte case study interview.

Clarify the question when needed: It is extremely important to answer the question being asked during the case interview. You will not be “docked” or judged for clarifying the question; however, if you answer the wrong question, you will not do well.

Develop a MECE framework: The framework should be tailored to the case and not a carbon copy out of a case book.

Structure, structure, and structure your answers: Deloitte is known for its market sizing questions. In these cases, it is especially important to write out and verbalize your structure before moving to solve the problem. Read our market sizing guide for more tips.

Mental Math

Practice mental math: The cases will include some quantitative questions – full stop. It is important to practice mental math ahead of time to solve the problems quickly and accurately. Utilize our free math drills to help you prepare.

Note Taking

Write notes throughout the case and keep your notes organized: Throughout the case, you will be given A LOT of facts. It may be hard to know what information is critical as you look back on your notepad. It can be helpful to put stars or boxes around the most critical facts, so you can easily reference them as needed

Synthesize your interim findings and clearly state how you got to your answer: At the end of each question, it is important to state your key conclusions and the supporting points.

Confident Recommendation

Provide a recommendation, and follow it with next steps: At the end of the case, you will be asked for a recommendation. It is critical to take a clear stance on the problem rather than a wishy washy answer or an “I don’t know.” To add more nuance to your answer, it is helpful to include the next steps the client will need to take.

Market Knowledge

Read about industry / market trends: Superstar candidates will link the themes in the case to real life applications and trends in the industry. It is helpful to have a broad understanding of trends going on in the market and tie them into the case, when relevant. For example, in 2022, key trends can include: shift towards e-commerce, supply chain shortages, focus on wellbeing, rising interest rates, etc.

Stay calm and take your time, when needed: Ultimately, it is important to keep your composure throughout the process (even if things don’t go right) and take a deep breath!

Ultimately, the key to mastering these skills is practice, practice, and more practice. Resources to practice Deloitte case interviews are included below.

Resume + Cover Letter Edits

Black Belt Deluxe

Your Deloitte case study interview will also depend on the part of the recruiting process you are in. The process typically involves 3 steps:

The 1st round of interviews usually involves one 30-45 minute behavioral interview and one or two 30-45 minute case interviews. Your interviewer will be a consultant or lower level manager.

The 2nd round of interviews is notably different at Deloitte compared to other consulting firms. Typically, candidates will go through one behavioral interview, one case interview, and a group case interview .

Deloitte, like any consulting firm, is looking for:

There are several ways to showcase these skills throughout the case interview:

Problem Solving Skills

Generally, candidates can showcase problem solving skills when developing the case framework. Specifically, the firm is looking for candidates to create a mutually exclusive and collectively exhaustive (“MECE”) framework. In addition, good problem solvers understand the “so what” implications from their findings and can link the implications to the client’s problem statement. For example, let’s say the case is centered around a top CPG player (think Proctor & Gamble) whose sales have been declining YoY.

For the framework, a superstar candidate will want to look at buckets like: market environment; competitive environment; client’s products; client’s capabilities (e.g., talent; e-commerce; marketing). In addition, during the interview the candidate may uncover that trendier brands are gaining market share vis a vis more traditional brands. A superstar candidate will then show the “so what” associated with the takeaway – for example, a potential implication is that the client should consider acquiring smaller, trendier brands or even setting up an incubator that can give the client first access to more innovative brands.

Analytical Skills

Deloitte typically tests analytical skills through the quantitative questions in a case. These quantitative questions include: interpreting graphs, performing mental math, and more detailed math questions. Market sizing questions are typically great ways to showcase your analytical skills, given you can break down an ambiguous problem into its discrete parts and complete detailed math problems to size the market. Superstar candidates perform the math correctly (and within a reasonable amount of time). They also check to make sure their answers make sense. Put the answer into context – for example, if a candidate sizes a market at $1T, a good candidate will communicate that the market size is likely too large and go back through and check their math.

Strategic and Logical Thinking

Strategic and logical thinking refers to the ability to push the problem forward in a logical way. Specifically, it’s important to understand what the insights are from the case and ask additional questions that build on the learnings (rather than ignore the learnings). For example, going back to the CPG example, imagine that the candidate learned that the client (a legacy CPG company) is losing market share because it is losing share on ecommerce purchases (the client is doing well in stores).

A logical next step would be to ask for more information around the ecommerce market and understand why the client is losing share in that channel. Asking questions about the client’s performance in stores would be viewed as a non-strategic question given performance in stores is not driving the client’s underperformance. In a true consulting engagement, there will be so many areas to dig into to understand the root of the client’s performance. However, given there is a limited amount of time to get to the root of the problem, it is important to use the 80/20 rule and not “boil the ocean.”

Common Sense

Common sense is similar to strategic and logical thinking. Here, Deloitte is looking for candidates to provide answers that are logically plausible. The answers don’t need to be correct, but they need to be reasonable. By testing for common sense, Deloitte is looking whether they can put you in front of a senior client.

Deloitte will be asking the same question to tens to hundreds of different candidates. At times, the answers will start to blur together. Superstar candidates will include responses that the interviewers may not have heard before. For example, going back to the prior prompt, let’s say the CPG client is losing out on Gen Z’s share of wallet and is looking for ways to increase market share. Creative answers to this question include:

Comfort with Ambiguity

As a consultant (especially a consultant at a generalist firm like Deloitte), you will be placed into new cases that may be out of your area of expertise. Although you may not be an expert on XYZ industry/functional area, you need to rely on your business acumen and problem solving skills to first dissect what you are being asked and then leverage your consulting toolkit to break down the problem. Translating this into a case interview context, it is important to show confidence throughout the case study interview and to not get flustered even if the questions are out of your comfort zone. In addition, you should never say “I don’t know” to any of the questions. Instead, press into the ambiguity and utilize your problem solving skills to provide a logical hypothesis

Additional skills to show throughout the interview include:


Communication can take a few different forms, e.g.,

Top-Down Communication

Top-down communication is also known as pyramid principle communication. The pyramid principle refers to starting with the answer to the question and then providing the supporting information afterwards. For example, if you are recommending your client (a CPG company) to acquire a specific target, a top-down answer could be: “I believe our client should acquire the target for 3 reasons. First… and so on. The key point here is that the answer (acquiring the target) was at the beginning of the response. For more on the pyramid principle and top-down communication, see Management Consulted’s overview here.

Structured Communication

Structured communication refers to the ability to group your answers into categories. For example, if you are listing off the supporting evidence for your point of view, you can say that you believe “x, y, and z for 3 reasons.” Then, before delving into each supporting point, you can enumerate the point, i.e., “first; second; third.” By grouping your supporting reasons into categories, it is easier for your interviewer to follow your logic and see your problem solving skills.

Oftentimes candidates rush through their answers (especially given interview nerves). It is important to go slow and breathe throughout the entire interview process.

While delving into your arguments, avoid upspeak (raising your voice at the end of the sentence)

Executive Presence

Throughout the interview, it is important to show that you can be around / hold your own with senior level clients (e.g., C-suite). Executive presence comes out in many forms including your communication skills, posture, dress code, and word choice. Avoid words like “like” and “umm.”

What to Expect in a Deloitte Case Interview

If you’ve never experienced a case interview, it can be a little unnerving not knowing what to expect. Take a deep breath, that’s completely normal! We’re going to outline below what you should be prepared for. If you do your prep work, especially if you work with an expert case coach, you can walk into your interview in a much more confident demeanor. But just as an overview, here are some things you can expect:

Deloitte values candidates with the ability to develop tailor-made MECE frameworks that reflect the specific case interview question. There is no cookie cutter framework that can be used. Utilize your business acumen and creativity to build a custom structure for the business problem in the case.

Deloitte case interview questions can span a wide variety of industries and topics, reflecting Deloitte’s breadth of work. For specific Deloitte case interview questions, please refer to Deloitte’s case interview prep tool here .

In addition, practice with Deloitte case studies in our comprehensive case library here .

Deloitte Case Interview Behavioral / Fit Questions

While the case interview is important for the Deloitte interview, the behavioral / fit portion of the case is also critical to prepare for. Unlike McKinsey which expects candidates to provide longer-form responses, the Deloitte fit interview mirrors that of BCG and Bain. Types of questions you can be asked include:

For an overview of consulting fit interviews, please see here . For 1:1 fit interview coaching with an ex-MBB consultant, go here .

Deloitte Case Interview Prep

Deloitte case interview prep is similar to MBB firms. The biggest mistake you could make, is not preparing adequately, and missing out on nailing your interview. You’ll want to give yourself enough time to really grasp the frameworks to be able to build your own to fit the case. If you need to brush up on your quant skills, then focus on that as well. The power move is to get an expert coach early, so that you know from the start what you’re weak and strong in. Don’t waist time doing things you don’t need to, and spend most of your energy bolstering those weak areas. Going through example cases is helpful for a lot of people, but you have to actually engage in casing yourself rather than just watching or readying about them.

Deloitte provides a handful of practice cases that are helpful depending on the consulting division you are interested in. These are actual Deloitte interview case study examples, and are provided through the Deloitte or third party websites.

Deloitte Case Interview Practice

Again, the most helpful way to prepare for Deloitte case interviews is to practice out-loud with a partner (e.g., an ex-consultant or an expert coach ). Reading about cases or watching others case will only go so far. To become an effective “caser”, you have to put boots on the ground and get your hands dirty.

Deloitte Case Interview Variations

The group case interview at Deloitte is the part of the recruiting process that is most challenging to prepare for. This is simply because it’s difficult to simulate a group interview, while of course practicing mock one-on-one case interviews requires just one other person.

During the group case interview, you and 3-5 other candidates will be given a case study to examine. You are given 10 minutes to review the materials and then asked to discuss questions about the case for 20 minutes with the rest of your group. Interviewers from Deloitte will be watching the whole time and will conclude the interview by asking the group questions for another 20 minutes.

This part of the interview is markedly different from other consulting firms. Your goal should not be to outshine or dominate the conversation – instead, do your best to show a collaborative spirit while speaking with a purpose when it’s your turn to talk. Deloitte places a high emphasis on teamwork and culture fit, so it’s important to show that you can be a great colleague.

Deloitte Strategy and Analytics case interviews mimic the cases you will see at other strategy-focused firms (e.g., BCG, Bain). If you are prepped for MBB cases, you will be well prepared for the Deloitte Strategy and Analytics consulting case interview.

The Deloitte Human Capital case interview will, not surprisingly, focus on human capital related issues. Topics can include:

Similar to the Deloitte Human Capital case interview, the Deloitte Enterprise Technology and Performance case interview will be more likely focused on topics in which the group focuses. These topics can include:

Again, the Deloitte Federal Consulting case interviews will likely be focused on public sector issues. Topics that could be covered include:

Preparing for these case variations doesn’t differ in most respects. You just need to be aware of the sectors that your role is engaged in. What specific issues does that sector encounter? Immerse yourself in that sector and get a firm grasp on those issues, as there will undoubtedly be questions related to those issues.

Concluding Thoughts

The Deloitte case interview is designed to mimic a real-life consulting case. To be a superstar candidate, you should show distinctive problem solving skills, business acumen, analytical skills, and creativity; you should also be able to deliver the case in a top-down way.

Deloitte case interview prep: the only post you'll need to read

Deloitte interviews are pretty challenging compared to regular interviews at large corporates. 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 have put together the ultimate list of facts and tips you need to know to maximize your chances of success.

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

1. Deloitte Consulting is bigger than McKinsey + BCG

Deloitte is a force to reckon with in consulting. In 2017, it generated ~$14bn in revenue from its consulting business line. This makes it about as big as McKinsey (~$10bn) and BCG (~$5bn) 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. The different geographies are therefore less integrated than at a firm like McKinsey which mainly grew organically.

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.

The type of work Deloitte S&O does is very similar to what you would do at McKinsey, BCG and Bain . 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.

And 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

Deloitte uses 3 steps in its recruiting process:

The exact format of each interview round will vary slightly by country. Below we step through the format that's currently being used in the US. If you are applying in another country you can still use this as a rough guide of what to expect. In addition, we recommend that you ask your local HR contact at Deloitte for more details.

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.

Next, first round interviews usually contain one behavioural interview (30 to 45mins) and one or two case interviews (30 to 45mins each). This is quite similar to what you could expect at other consulting firms.

Second round interviews are slightly different however. They include one case interview and one behavioural interview, like in the first round. But in addition, you will also be asked to complete a group case interview.

Let's step through regular case interviews and group case interviews at Deloitte in more details. You can also look at a few case interview examples on Deloitte's website .

3. Deloitte uses similar cases to BCG and Bain (candidate-led)

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 . As we have mentioned in the past there 7 types of questions you need to prepare for in candidate-led case interviews:

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 . You can also see an example of written case materials in this practice case published by Deloitte . To get a sense of what case interviews at Deloitte are like, you should have a look at the video below. As we mentioned, case interviews at Deloitte are candidate-led and therefore use the same format as BCG and Bain case interviews.

4. The second round also includes a 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:

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:

And the top 3 things you should really avoid doing :

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 about group case interviews, check-out our  separate detailed  guide  here .

5. Top behavioural interview questions asked at Deloitte

Behavioural interview questions asked at Deloitte fall into two categories:

We've written extensively about consulting fit / PEI questions in the past. But in summary here are the top 5 fit and PEI questions you should prepare for at Deloitte and other consulting firms.

Top 5 fit questions:

If you would like guidance on how to answer PEI questions, you can check our article on the topic here .

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 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.

6.2 Develop a consistent method to crack cases

One of the biggest challenges of interviewing with Deloitte  is solving cases that you’ve never seen before. Each case can be difficult, and you’ll have to perform well across multiple case interviews in order to get an offer.

As a result, it’s critical for you to have a consistent approach for solving cases. Deloitte  uses candidate-led case interviews, which can be broken down into the following types of questions:

If you can crack each type of question (within a case), then you can crack the overall case. To learn how to use this process to solve Deloitte   cases, you can use our BCG & Bain Case Interview Training Programme .  Deloitte  uses the same type of case interviews as BCG and Bain, so you can use that programme to prepare.

6.3 Learn from every mistake you make

During case interview preparation, the quality of your preparation is just as important as the quantity of time that you dedicate. It's better to do 20 cases thoughtfully than to rush through 40 cases. 

We recommend that you keep a notebook where you record improvement opportunities and specific things you did well for each case. 

The notebook and self-evaluation will help you to be more strategic (and efficient) with your preparation. It's also a good idea to go back and re-do old cases. For example, after you have done case #20, you could go back to case #1, to make sure you are not repeating the same mistakes.

The minimum preparation time required to succeed in case interviews is probably around 30 hours. However, if you don't prepare thoughtfully, it may take much longer. So take notes, be strategic, and keep practicing!

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:

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.

Hacking The Case Interview

Deloitte interviews are comprised of case interviews, a group case interview, and behavioral or fit interview questions. In this article, we’ll cover exactly what to expect in your upcoming Deloitte interview and how to best answer all of the different types of questions you may be asked.

Although most case interviews follow a similar structure, each consulting firm runs their interviews in a slightly different way.

We’ll cover in detail:  

Deloitte Interview Process

Deloitte is a massive company with over $46B in annual revenue, with about 40% of that coming from their consulting practice. They are the largest and arguably most prestigious firm of the Big Four. Some consider Deloitte to be the next best consulting firm after McKinsey, BCG, and Bain.

Given its size, Deloitte interviews may vary depending on the country of the office that you are interviewing for. However, the most common interview process consists of two rounds of interviews.

In the first round of interviews, you will have one 30 to 45-minute behavioral interview and one or two 30 to 45-minute case interviews.

In the second or final round of 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.

We’ll cover exactly how to answer each of these types of interview questions in the following sections.

Deloitte Case interview

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:

The Five Steps to Solve a Deloitte Case Interview

Deloitte recommends taking these 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. To learn how to create outstanding frameworks, review this comprehensive case interview framework guide .

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. 

Types of Deloitte Cases

Deloitte consulting is broken down into three groups:  

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. If you are interviewing with the Technology group, you’ll get a technology or IT case.

Deloitte Practice Cases

Below are practice cases created by Deloitte. We recommend working through these so that you know exactly what to expect in your Deloitte case interview.

Technology cases:

Deloitte Case Interview Tips

Deloitte provides the eight tips below 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.

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:

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:

Deloitte Group Case Interview Tips

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.
