I received a telephone interview 2 months after submitting my application, and was invited for an on campus interview 2 months after that. I was offered the position 1 month later.
The telephone interview was pretty straightforward: a series of about 15 questions, mostly pertaining to my previous experience.
The on campus interview included
-a dinner the night before
-3 individual interviews (hiring manager, another director and the dean)
-a groups interview with the office staff
-a presentation for 15 people including faculty, staff and researchers
-followed by a discussion period with the audience.
