Once they get an interview for the program, they need to make a good impression, be enthusiastic. It's also the time to make their wishes known if they prefer a certain type of "job."
My friend got in twice. The first time she was selected for food service, and she chose to decline, for a number of reasons, but part of it was that she didn't want to work at a food cart when she was a hotel management major.
When she applied a second time, at the interview she explained that she got in once before but declined, and when they asked her why, she explained that she really wanted to work in a resort because of her major, and she got in at the Poly!
It was a great experience for her, and the discounts were amazing!
