Went to a campus career fair and talked with representatives there. Was given information to apply online and had an interview set up within a couple of weeks. On campus 1-on-1 interview with the head of the co-op program. Mainly a cultural fit set of questions considering I was looking for my first job in college. Received an offer and was given two weeks to decide, they hire quite a few co-ops/interns so the turn around is quick. Worked there several semesters before graduation and it seemed to be standard that they would not let you know where you were going to be working until shortly before you needed to be there for the semester. Luckily, they do offer a great relocation payment if you have to move over 50 miles.

All of the questions were behavioral - they want to know how you work with others, how you react to obstacles, etc. It was one round of interviews and was conducted online.
