Nine interviews, including an initial phone screen with the recruiter. The total was split over three days and included some technical questions and "what if" scenarios. It was a fairly pleasant interview experience.

Can you describe a complex technical problem you solved in a previous project? What approach did you take to tackle the problem, and what was the outcome of your project?

Description of my background expertise + technical questions. The interviewer was very friendly and it was really like a chat. I felt very relaxed during the interview. The final questions were up to me (curiosity etc).
