Zara Cashier interview questions

Went to an open house, expecting to be interviewed as the ad said "come prepared for an interview"...wasn't a real interview at all. The manager took us to the middle of the store, didn't ask any real questions, or get to know candidates. I assume this "interview" was just to see what we looked like. Everyone came dressed very stylish, meanwhile the manager had on jeans and a plain plaid shirt -_- I expected more. We waited in line for longer than we talked with the manager. I was asked about availability and previous retail experience, all of which was on my resume, which she was reading as she asked the questions. That was it.
