I applied to the BCG Great China office. I was invited to super day in Philly. It was three 40-minute back-to-back interviews combining case and fit questions. The case questions I got depended on the interviewer's background. But they would keep challenging you to back up your logic. I think it was a fun process.

Multiple rounds with consulting case interview portions and fit portions. Each round of interviews had multiple interviews, and the interviewer gets more senior as you progress through the interview process
