Here's another tip...Put together a portfolio with certificates/degrees/awards/...don't forget a couple copies of your resume...Let your portfolio "speak" for you..it gives the interviewer(s) a better picture of you...A pad of paper is good to have so you can remember items and write down the names of the individual(s) interviewing you.

Oh, by the way, don't forget the "thank you" cards for everyone you spoke to..including the receptionist (better known as the "gatekeeper") ..give them to her to give the interviewers as soon as possible especially right after the interview.
