A lot of behavioral questions to gauge sales abilities and people management style/effectiveness as well as the basics, Why would you like to work for Best Buy (if your external) or Why would you like to work as a Sales Supervisor? If internal, be ready and able to speak to the business as well as trends. Be able to speak to your plan of action and be able to explain it within a couple minutes without going through it line by line.

Very streamlined Process, In-Person with general manager, General Interview questions but also a lot of sales experience questions and overall sales philosophy. My GM asked a lot of personal life questions too about my current job, lifestyle, and how bestbuy can benefit me outside of work.
