Went over my past experiences by going through my resume. Recalling details of experiences so that I had anecdotes to tell.
What impressed you positively?
The university hospital looks amazing.
What impressed you negatively?
Nothing really.
What did you wish you had known ahead of time?
It was my second interview in two years at that school so there weren't any unexpected surprises, though I did expect 3 interviewers instead of 2. But nothing really mindblowing.
