They follow a standard behavioral interview. The idea is each applicant gets the same questions so it is fair across the board. That is how I did it. But I have been in interviews with higher ups that just ask whatever they want. I prefer to do it the way they have it listed in the share point site. Makes it easier too. Most applicants do a good job of answering the questions.

Phone screen, an interview with a director then a third interview with 3 mangers doing a similar role in the organization. Standard behavioral questions. The process took 2 weeks but no offer or anything after.
