Abercrombie and Fitch interview question?

Hey Im an 18 y/o male and Abercrombie offered me an interview the other day when I went in to be a store model..I have a goatee and earrings, should I take them out for the interview? I was planning on wearing an A&F blue and white collared shirt, some A&F or Hollister jeans and someone told me to wear flipflops. I live in bay area california. Any advice on appearance and questions theyll ask me?
