Building on the last line of parent's comment, you should also research your co-workers ahead of time. Spend an hour or two googling the company, their email addresses, screen names, etc. If you're decent with Google, you'll find a lot. You should be able to get some idea of who you'll be talking with and working with ahead of time, which, in my case, helped me to be more confident during the interviews.

Anecdote: I recently came home from an interview at a startup, one which shall go unnamed, and decided to do more googling of their employees. I found that they had been taking parts of my cover letter, which was admittedly eccentric, and Twittering them amongst themselves, mocking me. How embarrassing, more so since I had just been in interviewing with them. Jerks.
