I applied on a paper application, and two days later they called me in for my first interview! It was a group interview, about 10 girls and 1 guy, the assistant manager was interviewing. It was a quick 15 minute interview, we started by introducing ourselves, hobbies, etc and then he asked basic questions like strengths and weaknesses, what can you contribute to forever 21, etc. I noticed a lot of the girls were a little underdressed, and copied each other's answers. He called me back 24 hours later for a second interview with the manager the next day.
The second interview was one on one, very fast about 10 minutes. The manager was really nice and asked the same questions, asked my availability.
I just got a call this morning and they offered me a position.
