There were 3 parts to the interview. The first was a one way video interview where you recorded yourself answering very basic questions (Why BlackRock? Why group XYZ?). Next was a half hour video interview with a member of the group. Some basic behavioral questions and others including "Describe something complicated to me in a simple way." This was a short interview so it was pretty fast paced/not as relaxed as I would have hoped for. Had time to ask 2 or 3 questions at the end. The final round was in New York and consisted of 4 half hour interviews. Two with associates, one with a director, and one with a managing director. Everyone was very nice and the interviews were pretty relaxed. It seemed like there few only a few set questions and most of the time was just talk to talk about something interesting on your resume a bit more or a mutual interest. I wasn't explicitly asked "Why BR?" or "Why group XYZ" during these interviews but I worked these answers into the answers to other questions and I feel like that really helped.

I first got a phone interview, mostly behavioral questions. A week later they invited me to an onsite interview, in which I was interviewed by four interviewers one by one, each 30 mins long.
