There is a HireVue plus three additional rounds. First round was with HR and consisted of simple behavioral questions. Second round was a take home case study plus an on the spot case study. We also had to do a roleplay scenario as if we were talking to a client. This round lasted an hour.

Multiple rounds, 1 case study/mock phone call, final with a senior which is casual and more personality based. I think they interview a lot of candidates, to my belief they offer a first round interview to many people. However, many of the interviewers are very friendly.
