How old do you have to be to work at Guess

You have to be 18! I learned this after having a group interview with a Guess manager. I believe I did well and, after a day, I received a phone call that I got the job.. she asked for my availability and then she asked if I was 18. I told her I was 17. SHE SAID APPLY NEXT YEAR! GRR :(.. :P
