It was a nearly a 3 hour interview with 5 different staff members. There were 3 behavioral interviews and 2 case interviews- one analytical and the other strategic. The interview was actually fun. It was great a) to see their process in action and b) to experience their culture first hand. Although the interview was long and slightly stressful, the interviewers were really kind, smart, and made me feel comfortable. Probably one of the most engaging interviews I've had.
