How to Prepare for Case Interviews

Welcome to our preparation tips for case interviews!  Whether you are just curious about case interviews or are planning to apply for consulting internships or full-time jobs, 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. 

Why are Case Interviews Used?

Case interviews allow employers to test and evaluate the following skills:

  • 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
  • Poise and communication skills under pressure and in front of a client

What are the Common Types and Structure of Case Interviews?

Common case scenarios include:

  • Profit – Identify reasons clients experience decrease in profits, identify ways clients can increase profits
  • Strategy – Assisting a client entering a new market, developing a new product, or investigating pricing or growth strategies
  • Operations –  Helping clients increase sales, reduce costs, improve bottom line
  • Market Sizing – Estimation scenarios and market-sizing questions that rely on quantitative abilities and logic to estimate a numerical answer
