It was a behavioral style interview, which was quite nerve-wracking! Every question began with, "tell me about a time when..." or "describe a time when you..."
Coming up with real life examples of your work on the fly is very difficult, and I left thinking of all the other experiences that came to mind afterwards.
I was interviewed by 2 people. The first was the person who would be managing me directly, and the second was a peer who was already in the position I was applying for, but working in a different office.
