Two to three phone screens, followed by 7-8 in-person interviews with managers, team members, and other concerned parties. Phone screens were based on very broad general knowledge of the subject area followed by the opportunity to ask questions. Interviews were a mix of HR mandated questions followed by general questions about experiences cited on my resume. No tricky or brainteaser type questions. Very broad technical questions about how you might approach a given problem, but nothing based on trying to find a specific answer.

Applied through internal recommendation via current employee that I know. ~2 months later, had the phone interview and it went well. Mostly technical questions related to position and questions about my background. 1 week later, I was invited to come on-site, where I had a full day (8 - 4:30) interview. Met with pretty much everyone in the group (17 people, either 1 on 1 interviews or 2 on 1 interviews) for 30-45 min each. Was pretty tired by the end of it but thought it went well. 4 weeks later I was told that they decided to make an offer to someone else, but I was in the top 3 candidates considered. Asked for specific feedback, and waiting on that now.
