The process took 3 weeks. I interviewed at Cintas (Cincinnati, OH) in Mar 2011
Interview
I went through a series of three different phases, where I was first interviewed, tested, and then intereviewed again in a round robin fashion where I met managers from all around the country. The first interview was the most nerve racking for me. The testing was extremely easy. In my opinion, the final round of interviewing was the easiest part. You meet with three different managers from different parts of the business. The atmosphere was very relaxed. They ask you simple behavioral and situational questions where they expect you to respond in STAR format. If you have a little bit of experience and went to a good school you should be able to answer these questions no problem. Be loose and you'll be fine.
Interview questions [1]
Question 1
Could you describe a time where you put in extra long hours on a job or project where you saw excellent results?
It was a fairly easy interview process. They asked questions about what I did in college as far as academics and internships. Nothing too difficult was covered. As long as you prepare, you will be fine.
Multiple Interviews and one in person. Nice people and good interview questions. Only negative was the follow up. I had to reach back out to see if I was still being considered or not.
They recruited me out of school. I had 8 rounds of interviews, and was promised the job in the second to last interview with the last being a formality. They rescheduled my final interview three times with three different people. Ultimately did not get the role.
