3 interviews with 3 different managers. It was pretty simple! After the 3rd interview, I received the job offer. The response time in setting up the follow up interview was about a day or so.

HR screen to start, then a meeting with two individuals currently in the role, and lastly a meeting with the director of the team. Primarily looking to see prior background, culture fit, willingness to be on the phones for good part of your day.
