Sears Sales Associate interview questions

Fairly easy and straight forward. I was asked about myself, typical questions of what were my strengths/weaknesses. And the rest of the interview was mainly to evaluate me as a sales representative, to see if I had enough social skills to hold my own on the floor. (Although there were many who didn't and still got the job). The lady interviewing me worked at the HR department and was very relaxed and nice. She then proceeded to give me options to work as a cashier or sales associate explaining that cashiers made more money by the hour but sales associates were eligible for omission, meaning if you sold a lot of stuff you would make way more than a cashier.
