I heard about the job opening from a friend. I arrived early and was promptly met at the door. They took me back to the lunchroom to wait until my interview started. Because it was near the lunch hour and the conference room was taken we sat in office chairs in one of the administrative offices. I was the only one being interviewed at the time, and there were 4 interviewers. I dressed professionally and my interviewers were dressed casually, as that is the type of dress they wear to work daily. After the interview they took me on a tour of the facility, (which is beautiful as far as labs go) and told me they'd get back to me in a few days tops. I brought copies of my resume but my interviewers already had copies, better safe than sorry though.
