Dependable Courier interview questions

A bunch of people set in the cafeteria. The interviewer asked irrelevant questions (Did you enjoy doing Amazon flex/doordash?). No questions pertaining to the job really. A lot of people who showed up were in jeans and tshirts. I was the only one professionally dressed and of course, I wasn't selected for the role. Completely wasted my time. Wouldn't even accept my resume. Told me I would be getting an email in 30 minutes and instead 5 days later received a denial letter. A day after, posted another urgently hiring post on indeed. They give me the impression they are not interested in hiring professionals or anyone, actually.
