UPS Supervisor interview questions

Emailed at 7am and notified of interview at 5pm. Weirdest/shortest interview/process I have ever been a part of. Group of five applicants showed up, escorted to an office, and waited. We were all interviewing for a PT supervisor position (differing shifts). Called back one at a time for an approximate 5-10min conversation with a manager. Sent back to room, while others interviewed. Seemed like UPS had already decided to hire all five of us, unless there were any obvious red flags during this quick "interview." Interviewer did not have our resumes, a list of who we were, etc...Had to ask and write down our names.
