A member of the HR staff and the supervisor for the specific department I was applying to conducted on-campus interviews. They were very friendly, professional, and interested in my specific experience and ability to contribute to the company. I was particularly pleased that they didn't ask very many of the robotic typical interview questions ("Tell about a time when you..."); instead, they listed specific tasks I'd be given in the role for which I was applying, and asked me abut any previous experience I had with similar tasks, and if not, how I might approach them. They also were happy to answer my questions about their personal experience with the company, and it was obvious that they loved their jobs and the people with whom they worked. This is one of the few interviews I've ever done where I felt like they were trying to win me over, and not the other way around.
