The Deloitte Case Interview: Your Key to Success in Consulting

Deloitte, is one of the " Big Four " consulting firms worldwide and has a rigorous interview process. The case interview is not just a test, but a reflection of the real challenges consultants face here every day.

In order to fulfill your consulting dream job at Deloitte, it is important that you are well prepared for the case interview there and know the most important information about the interview structure . Here you will find seven important points to keep in mind during your preparation as well as further literature from Deloitte.

The Interview Structure at Deloitte

Deloitte's interview process is not just about assessing your analytical skills , but also about understanding your personality , teamwork skills, and adaptability. The combination of behavioral questions , case presentations, and group discussions provides a holistic view of a candidate's fit with the Deloitte culture . Depending on the country you are applying to, the Deloitte interview may vary. In most cases, the interview process consists of two rounds.

The first round of interviews is divided into two parts and includes the Behavioral Interview, which lasts approximately 30 - 45 minutes and concludes with an initial Case Interview, which will also last approximately 30 - 45 minutes.

The second and final round consists of three components:

• Behavioral interview (30 - 45 min)
• Case interview (30 - 45 min)
• Group interview (approx. 1 hour)

Tip: Learn about Deloitte's core values and mission . Aligning your answers with the company's ethics can make a significant difference.

Prepare Yourself Sufficiently

The depth and breadth of your preparation can set you apart. Deloitte's cases are based on real-world scenarios , making it essential for candidates to be well-versed in global events, market trends, and industry-specific challenges .

Tip: Also, take advantage of case interview preparation groups or seek out case partners who have been through Deloitte's interview process before so you can get a feel for the relevant issues that are being actively addressed at Deloitte right now.

Take a Structured Approach

A structured approach is like a map during your case interview . It not only guides your thought process, but also ensures that you cover all the essential aspects of the case problem.

Tip: Use frameworks , but don't be limited by them. Adapt your approach to the nuances of the case presented and don't assume that your chosen framework will do the work for you.

Analytical Excellence is Key

In a data-driven world, the ability to dissect information, identify underlying patterns, and develop strategic solutions is invaluable. Deloitte's case interviews are designed to assess these very skills, often under time pressure .

Tip: Practice regularly with different case scenarios to sharpen your analytical thinking and data interpretation skills .

Communication: The Bridge to Success

In consulting, the solution is only as good as its presentation. Deloitte emphasizes clear, concise, and effective communication , ensuring that clients not only understand the recommendations, but are convinced of their value.

Tip: Practice with colleagues or mentors and get feedback on your communication style. Focus on clarity, brevity and impact . This will help you especially in the group interview!

Embracing the Unexpected

The real consulting world is often unpredictable. Deloitte's case interviews reflect this unpredictability and challenge candidates to think spontaneously and adapt to evolving scenarios.

Tip: Stay calm, confident and flexible. Use new information to refine your analysis and recommendations.

Continuous Learning and Feedback

The consulting landscape is constantly evolving. Deloitte values individuals who are not only skilled, but also committed to continuous growth and learning. Post-interview feedback is a goldmine of insight and highlights strengths and opportunities for improvement.

Tip: Be open with feedback. Every piece of advice is a step toward your consulting ambitions.

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?

Consulting casebooks are documents that MBA consulting clubs put together to help their members prepare for consulting case interviews. Consulting casebooks provide some case interview strategies and tips, but they mostly contain case interview practice cases.

While consulting casebooks contain tons of practice cases, there is quite a bit of variety in the sources and formats of these cases.

Some practice cases are taken from actual consulting interviews given by consulting firms. These are the best types of cases to practice with because they closely simulate the length and difficulty of an actual case interview. Other practice cases may be written by the consulting club’s officers. These cases are less realistic, but can still offer great practice.

The formats of the practice cases in consulting casebooks also vary significantly.

Some practice cases are written in a question and answer format. This type of format makes it easy to practice the case by yourself, without a case partner. Other practices cases are written in a dialogue format. These cases are better for practicing with a case interview partner.

MBA consulting casebooks can be a great resource because they are free and provide tons of practice cases to hone your case interview skills. However, there are several caveats that you should be aware of.

• Similarity to real case interviews : Some cases in MBA consulting casebooks are not representative of actual case interviews because they are written by consulting club officers instead of interviewers from consulting firms
• Quality of sample answers : While consulting casebooks provide sample solutions, these answers are often not the best or highest quality answers
• Ease of use : Consulting casebooks are all written in different formats and by different people. Therefore, it can be challenging to find cases that you can consistently use to practice cases by yourself or with a partner

Therefore, we recommend that you first use the case interview examples listed in this article and wait until you’ve exhausted all of them before using MBA consulting casebooks.

How to Use Case Interview Examples to Practice Case Interviews

To get the most out of these case interview examples and maximize your time spent on case interview practice, follow these three steps.

1. Understand the case interview structure beforehand

If case interviews are something new to you, we recommend watching the following video to learn the basics of case interviews in under 30 minutes.

Know that there are seven major steps of a case interview.

• Understanding the case background : Take note while the interviewer gives you the case background information. Afterwards, provide a concise synthesis to confirm your understanding of the situation and objective
• Asking clarifying questions : Ask questions to better understand the case background and objective
• Structuring a framework : Lay out a framework of what areas you want to look into in order to answer or solve the case
• Kicking off the case : Propose an area of your framework that you would like to dive deeper into 
• Solving quantitative problems : Solve a variety of different quantitative problems, such as market sizing questions and profitability questions. You may also be given charts and graphs to analyze or interpret
• Answering qualitative questions : You may be asked to brainstorm ideas or be asked to give your business opinion on a particular issue or topic
• Delivering a recommendation : Summarize the key takeaways from the case to deliver a firm and concise recommendation

2. Learn how to practice case interviews by yourself 

There are 6 steps to practice case interviews by yourself. The goal of these steps is to simulate a real case interview as closely as you can so that you practice the same skills and techniques that you are going to use in a real case interview.

• Synthesize the case background information out loud : Start the practice case interview by reading the case background information. Then, just as you would do in a live case interview, summarize the case background information out loud
• Ask clarifying questions out loud : Just as you would do in a live case interview, ask clarifying questions out loud. Although you do not have a case partner that can answer your questions, it is important to practice identifying the critical questions that need to be asked to fully understand the case
• Structure a framework and present it out loud : Pretend that you are in an actual interview in which you’ll only have a few minutes to put together a comprehensive and coherent framework. Replicate the stress that you will feel in an interview when you are practicing case interviews on your own by giving yourself time pressure.

When you have finished creating your framework, turn your paper around to face an imaginary interviewer and walk through the framework out loud. You will need to get good at presenting your framework concisely and in an easy to understand way.

• Propose an area to start the case : Propose an area of your framework to start the case. Make sure to say out loud the reasons why you want to start with that particular area
• Answer each case question out loud : If the question is a quantitative problem, create a structure and walk the interviewer through how you would solve the problem. When doing math, do your calculations out loud and explain the steps that you are taking.

If the question is qualitative, structure your thinking and then brainstorm your ideas out loud. Walk the interviewer through your ideas and opinions.

• Deliver a recommendation out loud : Just as you would do in a real case interview, ask for a brief moment to collect your thoughts and review your notes. Once you have decided on a recommendation, present your recommendation to the interviewer.

3. Follow best practices while practicing case interviews :    

You’ll most likely be watching, reading, or working through these case interview examples by yourself. To get the most practice and learnings out of each case interview example, follow these tips: 

• Don’t have notes or a calculator out when you are practicing since you won’t have these in your actual interview
• Don’t take breaks in the middle of a mock case interview
• Don’t read the case answer until you completely finish answering each question
• Talk through everything out loud as if there were an interviewer in the room
• Occasionally record yourself to understand what you look like and sound like when you speak

4. Identify improvement areas to work on

When the case is completed, review your framework and answers and compare them to the model answers that the case provides. Reflect on how you could have made your framework or answers stronger.

Also, take the time to reflect on what parts of the case you could have done better. Could your case synthesis be more concise? Was your framework mutually exclusive and collectively exhaustive? Could your math calculations be done more smoothly? Was your recommendation structured enough?

This is the most important part of practicing case interviews by yourself. Since you have no partner to provide you feedback, you will need to be introspective and identify your own improvement areas.

At the end of each practice case interview, you should have a list of new things that you have learned and a list of improvement areas to work on in future practice cases. You’ll continue to work on your improvement areas in future practice cases either by yourself or with a partner.

5. Eventually find a case partner to practice with

You can only do so many practice case interviews by yourself before your learning will start to plateau. Eventually, you should be practicing case interviews with a case partner.

Practicing with a case 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:

• Driving the direction of the case
• Asking for more information
• Collaborating to get the right approach or structure
• Answering follow-up questions

If you are practicing with a case partner, decide who is going to be giving the case and who is going to be receiving the case.

If you are giving the case, read the entire case information carefully. It may be helpful to read through everything twice so that you are familiar with all of the information and can answer any question that your partner asks you to clarify.

As the person giving the case, you need to be the case expert.

You should become familiar with the overall direction of the case. In other words, you should know what the major questions of the case are and what the major areas of investigation are. This will help you run the mock case interview more smoothly.  

Depending on whether you want the case interview to be interviewer-led or candidate-led, you will need to decide how much you want to steer the direction of the case.

If your partner gets stuck and is taking a long time, you may need to step in and provide suggestions or hints. If your partner is proceeding down a wrong direction, you will need to direct them towards the right direction.

Where to Find More Case Interview Examples

To find more case interview examples, you can use a variety of different case interview prep books, online courses, and coaching. We'll cover each of these different categories of resources for more case interview practice in more detail.

Case Interview Prep Books

Case interview prep books are great resources to use because they are fairly inexpensive, only costing $20 to $30. They contain a tremendous amount of information that you can read, digest, and re-read at your own pace.

Based on our comprehensive review of the 12 popular case interview prep books , we ranked nearly all of the case prep books in the market.

The three case interview prep books we recommend using are:

• Hacking the Case Interview : In this book, learn exactly what to do and what to say in every step of the case interview. This is the perfect book for beginners that are looking to learn the basics of case interviews quickly.
• The Ultimate Case Interview Workbook : In this book, hone your case interview skills through 65+ problems tailored towards each type of question asked in case interviews and 15 full-length practice cases. This book is great for intermediates looking to get quality practice.
• Case Interview Secrets : This book provides great explanations of essential case interview concepts and fundamentals. The stories and anecdotes that the author provides are entertaining and help paint a clear picture of what to expect in a case interview, what interviewers are looking for, and how to solve a case interview.

Case Interview Courses

Case interview courses are more expensive to use than case interview prep books, but offer more efficient and effective learning. You’ll learn much more quickly from watching someone teach you the material, provide examples, and then walk through practice problems than from reading a book by yourself.

Courses typically cost anywhere between $200 to $400.

If you are looking for a single resource to learn the best case interview strategies in the most efficient way possible, enroll in our comprehensive case interview course .

Through 70+ concise video lessons and 20 full-length practice cases based on real interviews from top-tier consulting firms, you’ll learn step-by-step how to crush your case interview.

We’ve had students pass their consulting first round interview with just a week of preparation, but know that your success depends on the amount of effort you put in and your starting capabilities.

Case Interview Coaching

With case interview coaching, you’ll pay anywhere between $100 to $300 for a 40- to 60-minute mock case interview session with a case coach. Typically, case coaches are former consultants or interviewers that have worked at top-tier consulting firms.

Although very expensive, case interview coaching can provide you with high quality feedback that can significantly improve your case interview performance. By working with a case coach, you will be practicing high quality cases with an expert. You’ll get detailed feedback that ordinary case interview partners are not able to provide.

Know that you do not need to purchase case interview coaching to receive a consulting job offer. The vast majority of candidates that receive offers from top firms did not purchase case interview coaching. By purchasing case interview coaching, you are essentially purchasing convenience and learning efficiency.

Case interview coaching is best for those that have already learned as much as they can about case interviews on their own and feel that they have reached a plateau in their learning. For case interview beginners and intermediates, it may be a better use of their money to first purchase a case interview course or case interview prep book before purchasing expensive coaching sessions.

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.

Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!

35 Case Interviews Examples from MBB / Big Four Firms

Studying case interview examples is one of the first steps in preparing for the  management consulting  recruitment process. If you don’t want to spend hours searching the web, this article presents a comprehensive and convenient list for you – with 35 example cases, 16 case books, along with a case video accompanied by detailed feedback on tips and techniques.

A clear understanding of “what is a case interview” is essential for effective use of these examples. I suggest reading our  Case Interview 101  guide, if you haven’t done so.

McKinsey case interview examples

Mckinsey practice cases.

• Diconsa Case
• Electro-Light Case
• GlobaPharm Case
• National Education Case

What should I know about McKinsey Case interviews?

At McKinsey, case interviews often follow the interviewer-led format , where the interviewer asks you multiple questions for you to answer with short pitches.

How do you nail these cases? Since the questions can be grouped into predictable types, an efficient approach is to master each question type. However, do that after you’ve mastered the case interview fundamentals!

For a detailed guide on interviewer-led cases, check out our article on McKinsey Case Interview .

BCG & Bain case interview examples

Bcg practice cases.

• BCG – Written Case – Chateau Boomerang

Bain practice cases

• Bain – Coffee Shop Co.
• Bain – Fashion Co.
• Bain – Mock Interview – Associate Consultant
• Bain – Mock Interview – Consultant

What should I know about BCG & Bain case interviews?

Unlike McKinsey, BCG and Bain case interviews typically follow the candidate-led format – which is the opposite of interviewer-led, with the candidate driving the case progress by actively breaking down problems in their own way.

The key to acing candidate-led cases is to master the case interview fundamental concepts as well as the frameworks.

Some BCG and Bain offices also utilize written case interviews – you have to go through a pile of data slides, select the most relevant ones to answer a set of interviewer questions, then deliver those answers in a presentation.

For a detailed guide on candidate-led cases, check out our article on BCG & Bain Case Interview .

Deloitte case interview examples

• Human Capital – Capital Airlines

• Technology – Galaxy Fitness

What should I know about Deloitte case interviews?

Case interviews at Deloitte also lean towards the candidate-led format like BCG and Bain.

The Deloitte consultant recruitment process also features group case interviews , which not only test analytical skills but also place a great deal on interpersonal handling.

Accenture case interview examples

Accenture divides its cases into three types with very cool-sounding names.

Sorted in descending order of popularity, they are:

These are similar to candidate-led cases at Bain and BCG. albeit shorter – the key is to develop a suitable framework and ask the right questions to extract data from the interviewer.

These are similar to the market-sizing and guesstimate questions asked in interviewer-led cases – demonstrate your calculations in structured, clear-cut, logical steps and you’ll nail the case.

These cases have you sort through a deluge of data to draw solutions; however, this type of case is rare.

Capital One case interview examples

Capital One is the odd one on this list – it is a bank-holding company. Nonetheless, this being one of the biggest banks in America, it’s interesting to see how its cases differ from the consulting ones.

Having gone through Capital One’s guide to its cases, I can’t help but notice the less-MECE structure of the sample answers. Additionally, there seems to be a greater focus on the numbers.

Nonetheless, having a solid knowledge of the basics of case interviews will not hurt you – if anything, your presentation will be much more in-depth, comprehensive, and understandable!

See Capital One Business Analyst Case Interview for an example case and answers.

Case interview example – Case video

The limitation of most official case interview examples is that they are either too short and vague, or in text format, or both.

To solve that problem for you, we’ve extracted a 30-minute-long, feedback-rich case sample from our Case Interview End-to-End Secrets Program .

This is a candidate-led, profitability case on an internet music broadcasting company called Pandora.

In 30 minutes, this candidate demonstrates the exact kind of shortcoming that most candidates suffer during real case interviews – they come in with sharp business senses, then hurt their own chances with inadequate techniques.

Here are seven notable areas where the candidate (and you) can improve:

Thanking Throughout the case, as especially in the opening, he should have shown more appreciation for the time the interviewer spent with him.

Structured opening The candidate’s opening of the case feels unstructured. He could have improved it by not mixing the playback and clarification parts. You can learn to nail the case in a 3-minute start through this video on How to Open Any Case Perfectly .

Explicitness A lot of the candidate’s thought process remains in his head; in a case interview, it’s better to be as explicit as possible – draw your issue tree out and point to it as you speak; state your hypothesis when you move into a branch; when you receive data, acknowledge it out loud.

Avoiding silence The silence in his case performance is too long, including his timeout and various gaps in his speech; either ask for timeout (and keep it as short as possible) or think out loud to fill those gaps.

Proactivity The candidate relies too much on the interviewer (e.g: asking for data when it can easily be calculated); you don’t want to appear lazy before your interviewer, so avoid this.

Avoiding repeating mistakes Making one mistake twice is a big no-no in consulting interviews; one key part of the consulting skill set is the ability to learn, and repeating your mistakes (especially if the interviewer has pointed it out) makes you look like someone who doesn’t learn.

Note-taking Given the mistakes this candidate makes, he’s probably not taking his notes well. I can show you how to get it right if you watch this video on Case Interview Note-Taking .

Nonetheless, there are three good points you can learn from the candidate:

The candidate sums up what he’s covered and announces his upcoming approach at the start and at key points in the case – this is a very good habit that gives you a sense of direction and shows that you’re an organized person.

The candidate performs a “reality check” on whether his actions match the issue tree; in a case interview it’s easy to lose track of what you’re doing, so remember to do this every once in a while.

The candidate prompts the interviewer to give out more data than he asked for; if anything, this actually matches a habit of real consultants, and if you’re lucky, your interviewer may actually give out important pieces you haven’t thought of.

These are only part of the “ninja tips” taught In our Case Interview E2E Secrets Program – besides the math and business intuition for long-term development, a key feature is the instant-result tips and techniques for case interviews.

Once you’ve mastered them, you can nail any case they throw at you!

For more “quality” practice, let’s have a mock case interview with former consultants from McKinsey, BCG, Bain, Oliver Wyman, Strategy& and many other consulting firms. They will help you identify your problem areas and give you actionable feedback, making your preparation much easier and faster.

Hi! This is Kim and welcome to another performance in the Tips & Techniques part of our amazing End-to-end program. You are about to hear a really interesting performance.

There is a common Myth that Profitability cases are easier. Well, for beginners, that’s may make sense, but I would argue that Profitability cases can be really tricky and candidates without good foundation will make about the same level of mistakes regardless of type of cases given.

The profitability case we are about to watch will show that. It’s a very unconventional

Profitability. It started out like a typical one but getting more and more tricky toward the end.

The candidate is fairly good in term of business intuition, but the Tips & Techniques aspect needs a lot of fine tune! Now let’s go ahead and get started! 

It’s actually a little better to playback the case information and ask clarifications. The candidate does not distinguish between the two and do both at a same time. Also, the candidate was asking these clarifications in an unorganized and unstructured fashion. This is not something terrible, but could have been better, especially when this is the very first part of the case, where the crucial first impression is being formed.

My pitch would sound like this:

“That’s a very interesting problem and I am happy to get the chance to solve it. First of all let me tell you my understanding of the case context and key objectives. Then I would like to ask a few clarifying questions regarding a few terminology and concepts. Both of these are to make sure that I will be solving the right problem.

So here is my understanding of the case: The client is ABC. Here are some DEF facts about the situation we just talked about. And the key case question is XYZ.

Does that correctly and adequately summarize the case?”

Once the interviewer confirms, I would move to the clarification part as follows: “Now I would like to ask a few clarification questions. There are three of them: No 1, … No 2, … and No 3, …”

You may see above pitch as obvious but that’s a perfect example of how you should open any cases. Every details matters. We will point out those details in just a second. But before we do that, it’s actually very helpful if you can go back, listen carefully to the above pitch, and try to point out the great components yourselves. Only after that, go back to this point and learn it all together.

Alright, let’s break down the perfect opening.

First of all, you hear me say: “That’s a very interesting problem and I am happy to get a chance to solve it”. This seems trivial but very beneficial in multiple ways:

1. I bought myself a couple of seconds to calm down and get focused. 2. By nature, we as human unconsciously like those who give us compliments. Nothing better than opening the case with a modest compliment to the interviewer.

And (c) I showed my great attitude towards the case, which the interviewer would assume is the same for real future consulting business problems.

You should do that in your interviews too. Say it and accompany it with the best smile you can give. It shows that you are not afraid of any problems. In fact, you love them and you are always ready for them.

Secondly, I did what I refer to as the “map habit”, which is to always say what you are about to do and then do it. Just like somebody in the car showing the drivers the route before cruising on the road. The driver would love it. This is where I said: “Let me tell you my understanding of the case context and key objectives. Then ABC…”.

Third, right at the beginning of the case, I try to be crystal clear and easy to follow. I don’t let the interviewer confused between playing the case vs. asking clarification questions. I distinguish between the two really carefully. This habit probably doesn’t change the outcome of how the case goes that much, but it certainly significantly changes the impression the interviewer has of me.

Fourth, in playing back the case, each person would have a different way to re-phrase. But there are three buckets to always include:

1. Who is the client 2. The facts regarding the client and the situation and (c) The key question and the objective of the case.

Fifth, after playing the case context and objectives, I pause for a second and ALIGN with the interviewer: “Does it correctly and adequately summarize the case?”. This is a habit that every consulting manager loves for young consultants to do. Nobody wants first-year folks to spend weeks of passion and hard-work building an excel model that the team can’t use. This habit is extensively taught at McKinsey, Bain and BCG, so therefore interviewers would love somebody that exhibits this habit often in case interview.

Lastly, when asking clarification questions, you hear me number them very carefully to create the strong impression that I am very organized and structured. I said I have three clarifying questions. Then I number them as I go through each. No.1, No.2, and No.3.

Sometimes, during interviews it’s hard to know exactly how many items you are going to get. One way is to take timeout often to carefully plan your pitch. If this is not possible in certain situations, you may skip telling how many items you have; but you should definitely still number your question: No.1, No.2; and so on. 

Just a moment ago, the candidate actually exhibited a good habit. After going through his clarification questions, the candidate ended by asking the “is there anything else” question. In this case, I actually give out an important piece of data.

Though this is not very common as not every interviewer is that generous in giving out data. But this is a habit management consultants have to have every day when talking to experts, clients, or key stakeholders. The key is to get the most data and insights out of every interview and this is the type of open-ended question every consultant asks several times a day.

To show of this habit in a case interview is very good!

There are three things I would like you to pay attention to:

First, it took the candidate up to 72 seconds to “gather his thoughts”. This is a little too long in a case interview. I intentionally leave the 72 seconds of silence in the recording so you get an idea of how long that is in real situations. But it’s worth-noting here is not only that. While in some very complicated and weird cases, it’s ok to take that long to really think and gather ideas. In this case, the approach as proposed by the candidate is very simple. For this very approach, I think no more than 15 to 20 seconds should be used.

No.2, with that said, I have told I really like the fact that this candidate exhibits the “map” habit. Before going straight to the approach he draws the overall approach first.

No.3. You also see here that the candidate tried to align the approach with me by asking my thoughts on it. As I just said on the previous comment, this is a great habit to have. Not only does it help reduce chance of going into the wrong direction in case interviews, but it also creates a good impression. Consulting interviewers love people doing it often!

Here we see a not-really-bad response that for sure could be much better. The candidate was going into the first branch of the analysis which is Revenue. I would fix this in 3 aspects:

First, even though we just talked about the overall approach, it’s still better to briefly set up the issue tree first then clearly note that you are going into one branch.

Second, this is not a must, but I always try to make my hypothesis as explicitly clear as possible. Here the candidate just implicitly made a hypothesis that the problem is on the revenue side. The best way to show our hypothesis-driven mindset is to explicitly say it.

Third, you hear this a ton of times in our End-to-End program but I am going to repeat it again and again. It is better to show the habit of aligning here too. Don’t just go into revenue, before doing that, give the interviewer a chance to agree or to actually guide you to Cost.

So, summarizing the above insights, my pitch would sound something like this:

“So as we just discussed, a profit problem is either caused by revenue or by cost. Unless you would like to go into cost first, let’s hypothesize that the problem is on revenue side. I would like to look deeper into Revenue. Do we have any data on the revenue?”

And while saying this, you should literally draw an issue tree and point to each as you speak.

There is an interesting case interview tip I want to point out here. Notice how the candidate responds after receiving two data points from me. He went straight into the next question without at least acknowledging the data received and also without briefly analyzing it.

I am glad that the candidate makes this mistakes… well, not glad for him but for the greater audience of this program. I would like to introduce to you the perfect habit of what you should react and do every time you have any piece of data during case interviews. So three things you need to do:

Step 1: Say … that’s an interesting piece of data. This helps the interviewer acknowledge that you have received and understand the data. This also buys you a little time. And furthermore, it’s always a good thing to give out modest compliments to the interviewer.

Step 2: Describe the data, how it looks, is there any special noteworthy trend? In this case, we should point out that revenue actually grew by more than 50%.

Also notice here that I immediately quantified the difference in specific quantitative measurement (in this case, percentage). Saying revenue went up is good, but it’s great to be able to say revenue went up by more than 50%.

Step 3: Link the trend identified back to the original case question and the hypothesis you have. Does it prove, disprove, or open up new investigation to really test the hypothesis? In this case, this data piece actually opened up new investigating areas to test the hypothesis that the bottleneck is within revenue.

My sample pitch for this step 3 would sound like this: “It’s interesting that revenue went up quite a bit. However, to be able to fully reject our hypothesis on the revenue, I would like to compare our revenue to that of the competitors as well.”

Then only at this point, after going through 3 steps above, I ask for the competitors’ revenue like the candidate did.

Notice here that I ended up asking the same question the candidate did. This shows that the candidate does have a good intuition and thought process. It’s just that he did all of these implicitly on his head.

In consulting case interview, it’s always good to do everything as explicitly as possible. Not only is it easier to follow but it helps show your great thought process.
