Pros
Flexible schedule for a college student, potential for task variety and some self directed work. Also a good way to learn about internal workings of a large variety of companies. If you are a business student you will be able to see the business concepts you study in action.
Cons
The company claims to be customer centered but it is completely profit centered. It also expects that its employees also be profit centered. Company is not particularly loyal, minor pat on the back for good sales rampant phone calls and threats if sales dip. Constant revolving door of full time employees that irritates customers and creates a death spiral of employees coming in, getting frustrated with an irritated customer, and walking back out. Also diminishing marginal returns on the amount of effort required to achieve dollars of commission. The amount of sales needed to equal a dollar per hour raise from another job is significant and also does not inspire loyalty in employees.
