Vantaggi
In sales, there is a relative sense of job security even when you are not that good. There are nice benefits like car stipends and insurance.
Svantaggi
If you really want to succeed you simply must become like those above you. While they may say they want people who "think-outside-the-box" I really don't think they really understand what that means. Senior management in the -+55 age range are stifling growth and causing real talent to leave. They would rather you go through the formalities and become a box checker as opposed to questioning why things are done how they are. They are building the future based on the ideas of the past that have succeeded with no variation for today's world. Middle management lacks any real backbone when it comes to allowing senior management to understand what is really going on. You can come in as a great thinker with great ideas but you will soon see others getting promoted simply because they are more like the person above them. The performance review is really somewhat of a joke.
