Semi formal, but comfortable and inviting. They want a smart friend that understands the Costco environment. They want someone that is sales driven and wants to make money, but also someone that is willing to be a team player, and do the background/administrative work.
The pay is commission based so you will not receive a raise unless you move into managment.
You get minimum wages plus you make very good commission on top of your salary and there is no limit on it, more you sell and more you make.
