I applied using the online application service at the University. I was emailed and offered a selection of dates for an interview. The interview lasted 20-30 minutes, and was basically three managers/coworkers asking scripted questions in turn. Just relax and give the information they want to hear. Don't sound forced, keep it natural - they are trying to see if they can stand working in close proximity to you for the foreseeable future. Following the interview, I was given a tour of the facilities, and was pleased by the atmosphere and general friendliness of the staff. I was contacted, again by email, with an official offer within a couple of days.
