Pros
If you already know how to sell, this place can make you a lot of money. All sales positions are commission based, with a $4 hourly rate. You will start off in the lower end departments, but if you prove yourself you can quickly make your way to selling TVs/PCs/Macs/Build components where you can earn a lot on busy days.
Cons
Commission means your earnings will be inconsistent. You are also not just a salesperson, so you will be often be working two hours either before or after the store closes, where you're only making your $4 hourly rate. Huge focus on numbers. Not only do you need to sell, you need to sell what the company wants you to sell. Every month you'll sit down with your manager and discuss the specific things your department is supposed to sell, and how you're doing compared to everybody else. Management will constantly be breathing down your back, even on slow days when there's not much you can do to drum up business. If you can deal with this, and intend to have a career in sales this can be a great place to work.
