Best Buy interview questions

I got a call about 2 weeks after I put in my application. FIrst interview was over the phone where the lady went over my availability, three departments i would work at, and some other thing. 2nd interview was a few days after and she asked me the same questions shown here mostly all about customer service and she told me should call in 3-4 days. A week later the manager called me to come in the next day for another interview, again, all questions are posted here which helped a lot!! He told me he would call in 3-4 days and he called within the hour to come in to interview with someone else. At this point you get excited thinking you got the job. I came in for the 4th interview and another manager went through the same application as the other two and she told me to try to sell her a box of tissues. It all went well and she told me she would call in 3-4 days. I was furious when I left, was I applying to be commander in chief? The 5th interview was with the GM, he asked me about what I would do if a coworker was stealing etc. He offered me a job at 8.25. This was a huge waste of my time.
