Best Buy is a great company with very talented team. There are 2 important components of the interview - first is the technical skills. There were some in-depth questions on NPV analysis etc. But most importantly, the second component of the interview tests the interpersonal skills. How well is the candidate being able to defend his or her position. The interviewers do apply pressure tactics to check if the candidate breaks down or helds to his or her position. Given the size of the organization and the growth, BB values the second component even more than the first one
