The interviewer was friendly and attentive. Although I was a bit nervous, it got easier as it went on because of their positive attitude. There were behavioral questions as I expected. I was really excited to work for them, but they found other candidates to fill the position. Make sure you know that if you pass the first on-campus interview, you will be making a presentation to members of the company at your desired workplace (at least for engineering positions from what I know) a few weeks later.
