It was a very pleasant experience. A few " Explain a time when ..." type of questions. The interviewers put you at ease immediately by giving you information about them and their role. You will know if you advance on to the next round because you will be escorted to the next interviewer, normally 2 or 3 on the same day. Never be afraid to ask for the job and more importanly make sure that you sell yourself. This is your opportunity to brag about all you've done.
