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 4 weeks. I interviewed at Best Buy (Milpitas, CA) in Oct 2010
Interview
I applied online, the assessment process took a while and had a lot of tricky questions. I suggest that the questions be answered truthfully and honestly. About a week after I applied I was called in for my first interview. I went through about 3 interviews total and the managers were very welcoming and looked like they enjoyed their jobs.
Interview questions [1]
Question 1
Why do you think you would be a good addition to this company?
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.
