Cintas Production Supervisor interview questions

I applied online, got called for interview with their HR pretty quick. Had interview then 2 more interviews back to back, was there for a total of 3 hours. They made me feel very comfortable, except for plant manager he was very tired, kept yawning, than ended with "we hire only the best, good luck" beat burst my bubble. was wondering if anybody knows if thats how they do interviews? Or if they simply stop interviewing if they decide not to hire you? Do I have a chance?

Applied On-line, was promptly called to set up an in person interview within a week of applying. Went through 3 interviews, HR Manager, Production Manager and then General Manager. Scripted questions. Seemed very interested in me and my background. Felt good about the job. Never heard back from them.
