Brief phone interview with recruiter. Week later behavioral phone interview with Manager (bad teammates, how you meet new people, dealing with ambiguities, etc.). Couple weeks later had an in person with a Recruiter/Partner, some behavioral questions followed by a case study about merging IT systems, was not too difficult and thankfully the interviewer was helpful in guiding the process because the case and questions were a little ambiguous. 3 weeks later I got an offer.

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.
