Very straightforward, as the recruiter gives you basically everything you need to answer the interview questions. 1st round is a standard HR screening about your experience and why you applied, second round is a case study (the easiest part in my opinion, as you basically prepare everything in advance, and the thrid round is 2 back to back 1hr interviews with managers. They are pretty friendly and seem to want to know why you are interested in the company and have a heavy focus on why you chose your past experiences (school clubs, internships, your college major, etc.) and how you liked them. Weirdly they harped a lot about what other places you were applying to and what your five-ten year plan was, so make sure you are letting them know you won't leave them in a year or two (which it seems like many do).
