I have an interview for an internal position (promotion) next week. One of the interviewers is my direct boss. The other two sit on either side of me. They know how I work and I'm sure they've already sized me up.

I don't know how we'll fill 1.5 hours. What do I wear? I wore a suit when I interviewed for me current position but that seems silly. I usually wear jeans and a blouse so I'm hoping slacks and a blazer will cut it.

Any tips on questions that might be asked or questions to ask?
