Crack the case

A case interview consists of a business problem taken from a real-life business situation from a Bain case or an example drawn from your résumé. It focuses on your analytic/structured approach to the problem rather than specific business knowledge.

The interviewer takes you through a series of steps to see how you tackle the various levels. The steps can range from identifying a critical issue, to breaking a problem into component parts, to finally identifying one or more solutions.

Preparation tips

  • Get started early.
  • Practice introductions, discussing your prior work experience and asking questions. It isn't just about "cracking the case."
  • With each practice case, work through the analytics so you are confident and efficient during this portion of the interview.
  • Don't spend too much time trying to learn the nuances of a particular industry. Focus instead on tackling common challenges faced by most businesses (e.g. declining profitability, merger integration, improving performance).
  • Practice with a diverse group of people to gain exposure to different types of cases, problems, solutions, and interview styles.
  • Learn to hone in on the most important issues using an "80/20" approach, instead of obsessing over the details.
  • Get comfortable making assumptions as you arrive at an answer. Your interviewer may not always give you additional data when you request it. Instead you might be asked: "What would you have to believe in order to be convinced our client should head in that direction?"
  • Practice "bringing it all together" with a one- to two-minute summary. It should include your final client recommendation.

Interview tips

  • Don't panic if your case is based on an unfamiliar industry. We're interested in how you analyze the problem, not your specific business knowledge.
  • We encourage you to ask clarifying questions. If you don't understand the case facts, it will be tough to ace the interview.
  • Approach the problem in a structured manner and then continue to refer back to that structure to logically work through the case.
  • Bain uses an "answer-first" approach by developing an early hypothesis and then refining/ proving it throughout the client engagement. Using this technique during your interview will help you reach an answer efficiently.
  • Don't get thrown off track by follow-up questions. Your interviewer is your ally and uses questions to get a better understanding of your thought process, not to stump you.
  • Always include a final recommendation to the question at hand—the best recommendations are practical, actionable, and will be implemented by the client to generate results.
  • There is no one "right" answer. Case interviews should be thoughtful dialogues about potential approaches to solving a tough business problem.
  • Relax and have fun! Case interviews are not isolated tests, but reflections of our work as consultants. This is a chance to show your passion and enthusiasm for the job.

"The biggest thing I look for is people who are structured thinkers. You need to prepare in your own mind how you will demonstrate this skill... laying out a tree at the beginning is effective, as is playing back the key questions and then planning your approach in such a way that I can really see your thought process."
