I applied via Teamworkonline, then had a phone interview, a few hours later was offered the internship. Seemed like they already had an idea of who they wanted to hire for the position. The hiring process may vary by department.

One round of interviews and after submission through the university website. I went to other events to make sure that my face and name were ones that they couldn't forget. I don't remember there being much to the interview process after submission of my application to the position.
