I applied through my university's career website, and was chosen for a first round on-campus interview about one week later. There was a mandatory information session for all who were chosen, the day before interviews took place. Meeting the campus recruiters in a less formal setting was definitely a plus. The first round interview consisted of pretty standard questions about your background and why you are qualified for the position. A couple weeks later they asked all candidates to take one of those standard behavioral and mental reasoning tests. Pretty easy and standard stuff. A couple weeks after that, the campus recruiter informed about six of us that we would be interviewing at corporate headquarters in Mason, OH. Three of us ended up going. This was a pretty standard day of presentations and interviews - tour of the facility, informal lunch conversations, and interviews with three different types of company managers. Just a standard behavioral interview, with questions coming straight off a sheet of paper. A couple of the interviewers seemed more inclined to just have a conversation, and were reluctant to even be asking the formal questions. Nothing out of the ordinary in what was about a two-month process.
