Kmart interview questions

The manager took me in her office to do the interview, she asked me alot of questions about my previous work experience, what would I do in certain situations, ect. After I was finished she got me waiting in the lounge for about 5 minutes then called my name and told me that I needed more job experiences. Problem is, I was more experienced than most of their workers, if you walked in that particular store, you would instantly know that most if not all of them don't know what there doing, especially the cashiers, everyday they only open 2 to 3 cash registers and they all will be backed up due to the cashiers not knowing what there doing, bad thing is that the cashiers have been working in the same position for years!
