Six thirty-minute interviews over the course of five weeks with the recruiter, hiring manager, senior manager, a counterpart AE, another manager, and finally sr. director. The interviews were more casual/informative - focused on experience and culture fit - and there was no presentation or assignment, which I was grateful for. The position wouldn't have started for another month after the offer, so it would have been a 2.5 month process end-to-end.
