Forever 21 , Sales Associate interview questions

I walked in the store and asked if they were hiring. The associate gave me an application and instructed me to speak with the store manager who was on duty once i filled out my application. I filled it out, came back in the same day, and introduced myself to the manager. The manger decided to give me an on the spot interview. She asked me a few questions and explained a few more specifics of the position. At the conclusion of the interview I was offered the position.

Went to the Forever Job fair in Manhattan, it started at 9 AM. Waited for about 3 hours on a line before my turn they were calling 10 people in at a time but once it was time for my group to go they called 20 people so they'd have time to see everyone. Basically the manager introduced himself and just asked one question went around the room then picked several people to stay behind while the other ones left and that was it. I waited on a line for over 3 hours for one generic basic question
