Case interview
If you are an undergraduate or MBA student who wants to get a consulting offer, you better do well on the case interview. If you ran a regression on consulting offers and good case interviews, the correlation would be 0.7 or higher. In non-geek terms, case interviews make the difference. You need to crush the case.
If you don’t do well on the case, it does not matter how good your GPA, industry knowledge, networking, and resume reads – you will not get a job offer.
What’s a case interview?
This format of interviewing is tough, but also a lot of fun. The interviewer gives you the problem and background, and it is up to the candidate to think through the problem, and selectively ask questions to solicit the information needed to get to a solution. 70% IQ, 30% EQ.
I tell younger MBAs to think of it as if you were interviewing a client employee to get some information. What kind of questions would you ask? What would your demeanor be? How would you engage in conversation to prevent it from feeling like a series of robotic questions? How would you build credibility? How would you coach the interviewee in the right direction, so they help you to solve the problem?
Thinking while smiling
It tests your mind & composure. Consulting firms want smart people who are not robots. Successful candidates can break down complex problems in their head, while maintaining their composure.
What they are looking for
In my mind, consulting firms wants people who are smart, logical, quick-thinking, well-spoken, and engaging. Alternatively, they DO NOT WANT slow, confusing, dense, garble-mouthed, boring robots. Consultancies want people they can immediately put in front of clients; they will bill you out to clients at $250-$400 a hour, and they want people who smell like success.
If you are not too familiar with case interviews, that is okay. There are a ton of resources, and it only takes 1-2 months to really understand the general mechanics of a case interview and start smoothing out the rough edges.
Resources
There are books and websites dedicated to “cracking the case”. Top MBA programs have consulting clubs, where they essentially collect case interview examples from the past. Duke even has some cases from the late 1990s. Career management centers typically organize case interview practice sessions where MBA alums go back to campus and run the MBAs through “mock case interviews”.
Start with the consulting websites
Consulting firms know that case interviews are tough. They don’t want you to fail, so they actually provide a lot of really good advice on their websites. The kinds of questions might come up, what things they look for in candidates, and they even provide case examples. This is the best place to start familiarizing yourself with the case interview format and approach. Look at these tips:
- McKinsey & Co case interview
- Bain & Co case interview
- Oliver Wyman case interview
- AT Kearney case interview (pdf, 1.2Mb, 35 pages)
- L.E.K. Consulting case interview
MBA consulting clubs
Many of the consulting clubs have put together “case books” with dozens, hundreds of sample case interview questions. These have been collected over the last 10 years, and it gives you a good flavor of they types of questions asked and the types of logical problem solving that you want to demonstrate. Use these to practice with friends and colleagues. It will warm-up your brain prior to case interviews. Search “case interview” + “pdf”
Case interview experts
If that is not enough, there are websites which offer advice on case interviews and provide services for a fee. These are the best two I saw:
It’s interview season in September.
Most management consulting firms and investment banks start interviewing as soon as school starts in September; they want the pick of the litter (best students). This means that for MBAs looking for full-time consulting offers, it high season to practice case interviews with friends. n my experience, it is good to practice with another person 20-30 times before your real interviews. Case interviews are a different animal, you should treat them accordingly.
Great post – especially helpful is the collection of casebooks. I haven’t seen anybody pull them together before. I’ll bet a lot of candidates find that super helpful.
Keep on keepin on
Thanks, you too. Do great work.
Really informative article! Thanks a lot!
I’ve been practising with these guys: http://mconsultingprep.com/problem-solving-test/how-to-prepare/
They offer Resume editing and Case Coaching too, but I found their Problem Solving Test materials best worth my spending, a really rich practice library.
Nice resource. Thanks for sharing.
Thanks for sharing! The link posted by Tony doesn’t work. Another helpful resource is http://www.preplounge.com/en/index.php?lang=en. It’s a nice platform where you can find case partners that match your skill level. Also they provide about 60 cases and you can consult experts ((ex-)consultants).
Thanks for the extra resource and will fix that link. Keep doing great work.
Thank you so much. This is extremely helpful
Great. Thanks for reading.
Great post and lots of helpful resources.
I had been practicing cases from the Emory Goizeuta casebook and found it really helpful. However I am no longer able to access the web-page as it asks for username and password.
I would be glad if you could send me the casebook as a pdf. Thank you!
Not sure I have that. Will see if there is another link somewhere.
Thank you – that looked like a broken link. I added this one, which I found online. This one works: https://community.bus.emory.edu/dept/ISOM/Shared%20Documents/consulting%20interview%20book.pdf
Thanks a lot! You are the best
Very helpful information!
Thank you very much!
Do you have any information about the differences between firms, position (new grad, career hire etc.) and regions, such as between USA and Japan?
What kind of information were you looking for?
Hello
I would suggest not using Consultingcase101.com as it is a bit of a scam. They have found free material and are charging for it and much of their content does not appeared to have been reviewed by someone with knowledge of case studies (I found one case study where the possible solution was someone complaining about why the interviewer was wrong).
Fascinating. Okay, thanks for the feedback. Taking off.
Thanks for sharing, will look into the sites for more information and education
