I began my the interview process with a phone interview with the HR rep for my area. We walked through my interview, and I learnt more about the company and asked some questions. This was followed my an aptitude test where my math, logic, and personality skills were tested. Then I had three interviews in one day with two service managers at my local branch and the general manager of the branch. These interviews were followed by an interview with the VP, where upon we discussed the best location for me (Cintas is all about the best "fit", so they want the location to be good for you and good for them). Then I went through more interviews with some GM's from branches farther away from me but that had a better fit than my local branch.
The interviews were standard, but difficult because of how long my round of interviews were with the service managers and GM that one day.
