Pros
In theory you have the ability to build and make your own deals and earn a lot of money, so in theory an aggressive sales person would do well.
Cons
Mid-Level Management is spineless, pathetic, and won't trust their employees to build the deals. They won't stand behind the employee proposals and instead make their own anyways. They then will propose what they want to the customer which is less aggressive to begin with and fold like a house of cards at the first sign of customer concern. Managers have no idea how to tell customers no and leverage Ansys' value or leverage the Salesperson's knowledge of the account, instead resorting right away to hemorrhaging margin and giving things for free. As a result, the formerly aggressive salesperson has all of their work diminished and then they earn a mere scrap of what they had aimed for as a result of mid-level management's ineptitude.
