Best Buy interview questions

I was called in for an interview to be a regular cashier at best buy. I arrived 15 minutes early but my manager interviewed me 40 minutes late. He said he was late because his previous interviews lasted longer than expected. I went into his office and the interview lasted about 30 minutes. I did not get the job because I got really nervous so he was able to tell. I said "um" too much and gave dumb answers to the questions. Some were basic questions but the other questions were really hard. He said he would make his decision the next week and he would call me but he never did. So if you're shy and nervous like me, make sure you have practiced and you are prepared for your interview at best buy.
