Zara Sales Associate interview questions

I applied online through their inditex website. i had applied to a position many time before and hadn't heard anything back, so i was really surprised when i received an email to come in for a group interview. It was a new store opening, so they were really looking for people. i dressed in all black and went to their Headquarter's. they had us fill out an application and then they brought us into a room. there were probably like forty of us. they collected all the applications and our resumes and basically started. i was the first one they called on. they basically like that i was opened on the weekends (this is something they really want!) and they asked me "what i think good customer service is?" and "what is my biggest strength?" i smiled alot and gave them an answer. after the interview, they said they'd call us back or email us in a week. i received a phone call offering me the job, a week later, and accepted it.

Group Interview....After hearing the same answer about 20 times makes me wonder how they are really judging these interviews. Literally the same answers over and over and over and then some more. The interview just saying "Good answer" it really was hilarious.
