Two rounds of interview. First one was 90 minute long interview consisting of basic resume review + technical questions + trivia. Second round is similar but with more behavioural aspect.

Tl;dr: Long interview process, very intellectually stimulating discussions, no offer due to internal restructuring. The interviewers were experts in the various skill areas required for the job, and they asked abstract, open questions. Each interviewer seemed highly qualified. Each interview was therefore an interesting discussion. At the end, the recruiter informed me that due to some internal restructuring, the position had to be cancelled.
