This was a while ago but I interviewed with several managers who were a part of the same org within the department I'd be working in. I enjoyed it but one of the interviewers ran out of questions and it was, in the end, a bit awkward when I was just offering information.

Shadowing with someone already in the role, several interviews with different managers. Standard questions, discussing previous experience, times adversity was faced, why the role was desired. Got a feel for the office culture while touring the building.
