Case Interview Preparation Tips

Welcome to our preparation tips for case interviews!  Whether you are just curious about case interviews or have an interview coming up, these tips and resources will help you feel more prepared and confident.

What is a Case Interview?

A case interview is a role playing exercise in which an employer assesses how logically and persuasively you can present a case. Rather than seeing if you get the “correct” answer, the objective is to evaluate your thought process. (Adapted with permission from Case In Point: Complete Case Interview Preparation by Marc Cosentino). 

Case interviews are very commonly used in the interview process for consulting firms and companies in similar industries. In the case interview, you will typically be given a business problem and then asked to solve it in a structured way. Learning this structure takes preparation and practice. You can learn more and practice using the resources listed below.

  • Analytical skills and logical ability to solve problems
  • Structure and thought process
  • Ability to ask for relevant data/information
  • Tolerance for ambiguity and data overload
