The Boston Consulting Group website has an amazing Interactive Case Library that students can use to practice case interviews. This tool allows you to select a sample case (I tested an Airline Case) and then a fictional interviewer starts the mock interview with you. You first receive background information about the client and then will work through multiple screens where you are asked a question (Ex. What factors should we explore for their impact on our client’s profitability?) and are provided with anywhere from two to five options to select as your response. At some points, you are asked to complete calculations or analyze graphs and it does a really nice job of mimicking a real case interview.
When you finish the case, you will see a short recap and a summary of your results across 4 areas (Rigor, Structuring, Business Judgment and Synthesis). In addition, you will see how you compare to the Average and the 90th Percentile. Enjoy!
