Just a salesman with a nice name, doing the same thing. If you are a big company, training is to let you do sales for a period of time first, and then, if you have the opportunity, behave well enough, just like promotion, do sales management. For a small company, it is a pure salesman. Of course, if there is a vacancy to be mentioned, people trained by the company will be given priority in the case of similar ability. This is the same type of reserve cadre that many places are recruiting.
