HR screen, followed by phone interview with hiring manager, then 2 half-day on-site interviews meeting with members on the team ranging from junior staff to senior management. Also ran a background check. I enjoyed meeting the team and thought the interview process was typical for the industry. I did not receive an offer, which is fine, but would have appreciated better follow-up from HR. HR would tell me they would be contacting me "next week" several times and each time gave a reason for the delay. After a month of this I got the hint and realized they were just stringing me along. If you decide to go in another direction for someone who made it to the final round a polite email to let them know would be appreciated.
