Typically, Best Buy has three stages for their interview process, screening over the phone, in-store supervisor or manager interview, and a final interview with the general manager of the store.
The process took 2 weeks. I interviewed at Best Buy (Saint Louis, MO) in Sept 2009
Interview
I applied online and went in on September 30th for an interview with the mobile sales manager. He asked pretty basic questions like describe yourself and what do you want to go into. He described the company and he also described himself. My interview process in on-going and i have my final interview with the General Manager tomorrow. Hopefully I get the job. I will let everyone know how it goes and what exactly they ask me. My best advice for you is though, if you really want the job, you need to bug them. Don't expect them to take the initiative because they get so many applications. If you want them to consider you then call in or better yet, go in on a day that you know the hiring manager is there (you can find out by calling and asking) and ask to speak to her when you get into the store. If he/she is free then ask them to take a look at your application. This is what I did and it worked for me seeing as I had applied 3 times before and had never gotten a call back. Good Luck everyone.
Easy questions like "what would you do if a coworker was stealing from the company?". Managers were very nice and easy to talk to. Overall good experience and simple for a college student to apply.
I would say that knowing how mobile phones tie into daily life will help you frame your mind for the interview. Also good to know the different ways phone plans work.
