I applied for the position by submitting my resume through my university's online career website, and then they invited me to an on-campus interview. I had a one on one 30 minute interview and it was really relaxed and informal. It almost threw me off because it was so informal and kind of off topic - like one question he asked was to name any 3 people I'd want to meet. It was very casual so it was kind of hard to gauge if I did well or not.
