Round 1 - Phone screen with HR. She asked very high level questions about my background and talked about the job some, including salary expectations.
Round 2 - Phone screen with the hiring manager, in this case, a VP. Questions were more fit/culture than technical. She gave immediate feedback at the end of the interview and invited me for onsite. I literally received an email from HR within an hour of hanging up.
Round 3 - Onsite interview with some immediate team members, including one person who would be reporting to me.
Round 4 - Final onsite with others who would be impacted by my position and had a stake in hiring the right person/fit.
Offer - Email came asking when I would have time to speak. Offer came over the phone.
