Best Buy interview questions

I got 2 phone calls prior to my interview just scheduling my interview, i was reffered by an employee(this is the easiest way to get your application noticed). When i went in they called it my second interview. They asked me basic questions, such as- Explain a time when you went that extra mile and why?, Name a time when you were not the leader but rose to being a leader instead. They also gave me the shrink question about if u catch an employee stealing-what would you do, i said 'report it to a manager" then my interviewer asked what would you say and why. i answered "i would tell him i saw this employee doing suspicious activity" and then the next part i said blew my interview- I added that he should get a second chance if it were a minor item. I later found out that was the exact reason i didnt receive the job. They also asked me what super power i'd want if i could have any one. It was a pretty easy interview but lasted me about 30 minutes or so.
