Pros
It's the perceived fun atmosphere that will draw you in. And then you find out about the awesome discount. You can put a face to the name of your CEO as you see him constantly throughout the year in training videos. Pretty decent discount.
Cons
Once you achieve a certain level in leadership the opportunities to advance are extremely slim. Promotions are based on how chummy you are with management, not based on track record and proven performance. I was constantly being told that I could expect a promotion after a "successful holiday season" for 4 consecutive years. As a supervisor you are expected to do the work of store management while receiving very little recognition for a job well done. Getting time off (even with several weeks advance notice) often takes an act of congress and puts you directly in the path of an inquisition that cannot be avoided. Expect phone calls when out of the store to handle issues that store management should be able to handle; screening phone calls is not an option as you will be swiftly reprimanded upon returning to work. The work done is never good enough. Instead of being proactive about the economic downturn, Best Buy has reacted by looking for a quick fix which has resulted in shifting focus on a seemingly daily basis and giving off a "flavor of the week" mentality based around whatever hot-button metric territory staff is pushing that day.
