Cintas Production Supervisor interview questions

Its a long interview process filled with false hope. I spent a month going through the interview process, got a copy of the handbook, tour of the facility, met a VP, and got to the final interview....At the end, I got a generic rejection letter 3 days after a VP Meet and Greet. I am looking to better my career and while I still feel Cintas looks like a decent company from the outside, the interview process is way too long and filled with false hope.
