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.
I applied online. The process took 1+ week. I interviewed at Best Buy (Pittsburgh, PA) in Feb 2011
Interview
application interview online, receive a phone call from the store to schedule an interview with a supervisor, and a third interview with the general manager.
Interview questions [1]
Question 1
Describe a time where you demonstrated positive leadership? What did you do to specifically show your leadership skills.
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.
