The first interview was an on-campus case-interview. Interviewer first asked me a little about myself and then got straight to the case. It was a very simple revenue-costs case about the raising the credit limit of certain credit cards. For final rounds, we were flown to the site where the following day, there was an interview powerday. 3 interviews - one case, one fit, one behavioral. The case was another simple math case interview. Behavioral was the standard "Tell me about a time when...". Fit was basically a chat with a recent hire.
