Hired in from crew and raised to do the interviews, all they were looking for was ambition, energy and sometimes most importantly, just a smile. I'm not sure if they are still using the same model but when I was doing it they were looking for 13 characteristics, and would ask questions designed to highlight these attributes,
Polite
Hospitable
Smart
Ambitious
Curious
Happy
Respectful
Honest
Presentable
Conscientious
Motivated
Infectiously Enthusiastic
High Energy
These are said to be not teach-able, either you have them or you don't, so just read over them, and embody them in your every day life forever, go ahead, drink the Kool-Aid, I've met some of my best and lifelong friends from this place, and though I left, I wouldn't trade my experience for the world
