It was very slick, they have a well defined process which HR will talk you through. it will vary team to team a bit but they do explain things. Found I needed to ask some clarification questions though as there is a fair bit of complexity around their remuneration

Interview process was standard, but they ended up going with an internal candidate, per expectation. I had three interviews, with the hiring manager attending each. It was a little disappointing to find out they had just been going through the motions of interviewing, when they were already planning to hire internally.

Screen with the recruiter, then interviews with peer product managers and a culture fit interview. Recruiter checked in after every round except the last one. They didn't communicate a decision explicitly, but sent me a survey about my experience, at which point I figured they weren't going to hire me.
