Pros
It is a fun place to work, you get to meet great, cool people, the pay is not bad for the work, and the employee discount is amaizing. They are like my second family. As an example, my store is really laid back and will host fun games. Such include going outside and playing football before the store opens on Sundays. We have a softball team which play's other Best Buys around the city. All the departments try to help each other out and we all try to succeed while having fun. Managers don't harp on us for not selling a certain number of things and we all approach our success in qualitative terms.
Cons
It can be a little stressful if you don't know what you are doing and the rules and systems of Best Buy can make it really confusing. Certain customer service issues are the worst as customers always think we screw them over or blame us for their product not working and request we fix it for free, even when it is only under a manufacturer's warrenty. Also, we try to get so many things at once in terms of metrics for the store. On each sale (think computer sales for this example) we need to get not only the proper product, but any accessories, Geek Squad services, appropriate software, service plans, branded payments (Best Buy Credit Card), Reward Zone, and anything else to make sure the customer is getting as much benefit as possible out of their experience. Trying to balance getting all these things on each customer without being longwinded and seeming like you are forcing them into a deal is a bit hard to do.
