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 3 days. I interviewed at Best Buy in Jun 2011
Interview
I applied online on a Tuesday, they called me back the next day, then I had 2 interviews the next day, one with the mobile manager, and one with the csm, then I went and took a drug test and got hired in the following week. It did take them a month to run my background check for some reason, so I didn't officially start until about a month after I was technically offered the position.
Interview questions [1]
Question 1
Describe a time you had to work with a difficult customer
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.
