I was an internal applicant for this position, and the hiring manager was a very no-nonsense kind of manager.

He ran interviews for a week, then made a decision.

The interview lasted about an hour and consisted of mostly open-ended questions, trying to discern how I would handle particular scenarios and what experience I had that I could draw upon.

Since this particular interview was run by a single person, it was difficult to anticipate what would be asked. The question that was most unexpected was, 'What single word describes your approach to your work?' I ended up giving them a list since I couldn't come up with a single word.
