They don't ask for references for the college program. With the number of people who apply, it would be impossible for them to really follow-up on this info for everyone. they may do it if they are on the fence about someone, though. Really they use this just to reference any previous work experience someone may have. Most of the positions this doesn't play a major role in. Some, like concierge, may be of a higher consideration. Also if someone is interested in a position that requires significant money transactions (like Vacation planner), having previous experience with credit card transactions or handling large sums of cash may help.
