Come prepared to the interview. Bring samples of your correspondence, writing samples, projects you've completed. Understand how your skills will benefit the company. Most of all, LISTEN. An admin person is support for managers and executives. If you can't listen while being given direction, you won't be effective at your job. A pad of paper and a pen *at all times* is a must. I always prefer the person who listens intently and then asks succinct questions over the person who tries to guess what I'm saying and then misses key points. For the rest, just be yourself. Good luck.
