In our round one interviews, we do one 30-minute strategy case (e.g., a profitability question) and one 30-minute behavioral interview that also includes a market sizing component. We factor in general strength of communication and clarity of their "story" as well as their quantitative performance and strategic thinking in the cases. For final rounds, we include a group case that tests teamwork and ability to form a logical argument with data to make a case for or against a business based on information about its market, its competitive positioning, growth trajectory, etc. The final round candidates all tend to be very strong and we are selecting those who are truly exceptional.
