Phone screen, meetings with product representatives, engineers, and engineering leadership. I want to call out the technical interview with engineers particularly; it was an excellent balance of technical sophistication, open-endedness, and flexibility. Probably the best technical interview I've had that asked a candidate to show expertise while not shoving them into some algorithmic challenge that doesn't look anything like real work. Similarly the interview with engineering leadership was free-flowing and permitted a lot of expressiveness from the candidate while remaining focused and relevant.
