Applied through school's career center. Had on campus interview, which was split into two parts. First thirty minute case interview with one person followed by another thirty minute behavioral with someone different. Case interviewer was nice but given a tough case to work with. Behavioral interviewer less friendly asking questions from list. Second round interviews were the next day with one long interview with two interviewers

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.
