Best Buy Saled Associate interview questions

I waited a long time for someone to interview me, which I heard is common for this company. I didn't mind because I needed a job. The interview was generic mostly- he read from a script and wrote down my answers. One thing I did find odd was that the manager conducting the interview brought in another employee to show him how the process worked. This made me uncomfortable, especially when I heard the two right outside the door discussing my answers, and pros and cons. I found out later that this other employee wasn't even training to be a manager, which I found especially unprofessional. Overall, I gave the usual interview question answers (which can be found at any job-seeking website) and was apparently qualified enough for a position in the Mobile Phone department, which I had no prior knowledge or experience in.
