There were two phone interviews prior to an in-person, day-long interview. I had to give a talk on prior work, and then 5 pairs of people each taking half an hour. I was taken to a nice lunch. I was not given a deep understanding of the concentration of decision-making processes at the very top of the company, and led to believe that I would have more authority and responsibility than I ended up having.

Initial screening call with future direct report, followed by an interview panel giving a presentation and having 1-on-1 meetings. Finally, follow-up call with future direct report. Job offer letter then 1-2 weeks to make decision.
