I applied through university. The process took 4 weeks. I interviewed at Cintas (Atlanta, GA) in Oct 2017
Interview
I approached them at a career fair and I was offered an on-campus interview the next day. After that, I was selected to move forward to Round Robin interviews at their local warehouse and office. This consisted of a grueling process of 7 interviews with their GMs and other executives, a warehouse tour, and lunch. While most of the interviewers were very nice and inviting, the process itself is really stressful and by the 4th or 5th interview, you are extremely tired and most likely repeating things you've already said. Dress extremely professional and do not wear any jewelry such as nose rings. Even though this mentality is extremely outdated, I could tell Cintas definitely did not like that I wore my nose ring, even though it was for a religious purpose! Also, after the round robin interviews, we were told we would get contacted within 5 business days, but I did not get an email for almost 2-3 weeks. At one point, I stopped expecting it too. When I finally did get an email, it was a concise paragraph with the usual "we regret to inform you" stuff. Nothing about what went wrong at all, so that was discouraging.
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.
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.
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.
