I interviewed at Best Buy (Richfield, MN) in Aug 2010
Interview
Very professional, met with three different leaders (supply chain, marketing and senior buyers), it was timely and the whole process took about a week. There were the typical behavioral-based questions. The interview was internal so it was a faster process than the typical external interview. I did not have a phone screening and was immediately scheduled, so it really depends on the need of the position and urgency to fill the role.
I had an interview with a few people from buying and we went to lunch. I got a tour of the plant and felt like they really took time to get to know me. They asked behavioral interview questions and questions specific to the role I was applying for.
two interviews to go through, mostly laid back but depends on what role or who with. The culture is typically more business casual and that is carried through in the interview process as well.
