Applied on my campus' recruiting system. Got invited for an on-campus interview on a Monday. The interview was to be 1 case interview and 1 behavioral interview (both with managers). Got an offer to be assisted with preparing for the case interview. Was called for the second-round case interview scheduled for the next day with a Partner by Monday evening. Was told by the recruiter that I'd hear back in 1-2weeks later. I heard back in 3 weeks. Preparing for the case interview with a Deloitte employee helped a whole lot. Wasn't taken by surprise by anything. There's also some helpful information on the website.

I went through two interviews. The first interview included the behavioral part and case part. The second interview was with a managing director, and the entire interview was about solving a M&A case.
