Best Buy Sale Representative interview questions

You have to fill out an application on a computer inside the store or online, take a personality test,and they will call to setup an interview time. The interview was done a while ago, but from what I remember it was quite strange and provocative. The typical interview questions such as tell me about yourself, what can you do for this company, educational background, customer service questions are asked. When it comes to the specific questions thats where things went south. My interviewer was a lady and she was tired because I was the last one to be interviewed for the day. She wanted to know what I knew about electronics, especially computers.What do you know about computers? What is your speciality in this area? I told her I knew a lot about wireless routers and networking giving her specific details. She then kept asking me the same questions over and over not statisified with any answer I gave her. I told her I knew about video cards, computer programs, etc., but she did not care. Apparently, I could tell she was already rolling her eyes and wanting to be out of there for the day. She was not even listening to what I was saying. I probably had the worst interview exprience since I started applying for jobs. I already knew things did not go well and she stopped asking questions after that. But I did ask her about what the position does. You wont be staying in oner area for long so they will switch you around to either the computers to games, etc. They want you to know about a lot of the stuff they sell and be an outgoing person. Make sure you do your homework before the interview. Make sure you know things about computers, PC games, Iphone, Apple, DVDs, Music, hardware, Tvs, cash register, customer service, etc. They like you to troubleshoot problems with electronics. Also, I had a different experience than what most people would have had. My interview became difficult, but others may have had a a better experience. Look at others and see what has changed. Mine was done a few years back.
