Cintas Customer Service Representative interview questions

Applied online and within a week, received a call for a phone interview. Phone interview was with a current account manager, and was very general in regards to past experience and expectations of this role. Was informed that I would hear back by the beginning of the following week, which I never did. Two weeks later, I reached back out and they said that their manager is the one doing follow up so I should hear from them. It's not been three weeks and haven't heard anything about moving forward or not, which is surprising for such a large and established company.
