Cintas Sales Representative Uniform interview questions

After going through four interviews as well as a ride along and reaching what they called the "final" interview, I was not offered the job. This is despite senior management telling me I "nailed" the interview. Also after giving up hours (probably about 8-10) of my time over 2 weeks. Even after all this I got a generic "sorry but we are not moving forward with your application" email rather than a call which leaves me wondering what happened. I reached out to the manager asking what I could improve on to help me with interviews in the future and I was ignored. Very unprofessional.

Lengthy interview process with 5 rounds and a ride along with a rep. Mostly STAR questions and walking through your resume. Will start with a phone call then an in person followed by several zoom calls with higher ups all the way to the VP of sales
