I had the same exact experience in high school. I think I found the ad online and the interview was at the mall. I knew something was off but couldn’t pin it down exactly at the time (now I know it was probably some MLM type scam). I stuck around and was “interviewed” but didn’t accept anything. Later they called my house and my parents told them I wasn’t interested.

I hadn't even considered I might be too good to sell perfume in a parking lot until that moment, but it turned out that I was.
