2 in-person interviews. One was formal with associate director of engineering and a senior engineer. I supposedly got passed up for that position and was contacted a week later to set up another interview with the person that would end up being my manager. Second interview was casual. Was offered the position on the spot.

It was a phone interview and that was all. I was asked about Project Management and MS Office skills. Also about my projects during my undergrad and grad studies. It lasted for about half an hour and that was all.
