Sales people receive a lot of training, but must follow a strict presentation that many customers simply don't have the time to listen to. It makes sense how they try to steer the sales call, but it also makes you not only sound like a robot and sometimes frustrates the customer. They do quality work, but not very competitive. Consequently, there is a lot of turnover.
Good entry level job with a lot of training
Structured sales presentation and very high margins - not very competitive
