I talked to a recruiter at my school's career fair and he scheduled me for an on-campus technical + behavioral interview for the very next morning. Two weeks later I had a telephone interview with my potential supervisor. He mainly asked me to go in further detail about all the projects I have done or been involved in, and then described what he is working on and if I have experience with anything related to it.

Met at career fair and was asked for an interview the next day. They were very nice but asked many technical questions about circuits, signals, and digital logic. Did not give a heads up that it would be a technical interview.
