There were many rounds, but that may be the norm these days. I can recall a screening with a recruiter, talking directly to the hiring manager, talking with several people from the team at once, speaking with a higher level manager, a personality assessment and a skills assessment. The people interviews were very rushed at ~30 minutes. It felt a bit impersonal and I received a call after all of these rounds only stating they decided not to move forward and could not give me any feedback. While there wasn't anything overly negative, I wouldn't call it a positive experience.
