Cintas Sales Representative interview questions

First there was a phone interview. It was very pleasant and lasted about half an hour. Two weeks later I received a call to set up an in person interview with the hiring manager. I met with him and he asked me several questions about my background, then did two role plays. He then folded his hands and asked if I had any questions. Well, 1 hour and 15 minutes went by and we finished the interview. I though I did very well and engaged my "client" and asked all the pertinent questions. He then said I would hear from him the following week for a "ride with" and then an interview with his boss and finally an interview with the VP of sales. I never heard from him again until I emailed a week later to ask what the timeline will be. Two days later I received a thanks but no thanks letter. I sent all the necessary correspondence and thank you emails throughout the process. Not quite sure what happened.
