And be yourself!

If it is the nurse manager interviewing you, I know that many will be sizing you up for your preceptor, at least where I work they do...and they do a great job matching personalities!
The advice on having someone interview you is a great one! When I was in nursing school, in the dim dark ages, we had Nursing Leadership and part of our class was dressing as if we were going to an interview and being interviewed by the head mistress of the school....it was eye opening! She told us how many times we said...um, umm

But it made us ready for our interviews!
