Greed!
That is the only reason why. The leadership thinks they can pull in the same revenue with new sales teams just out of college. Absolute nonsense. These decisions seem to be made on baseless assumptions, and the sales and marketing leadership have no clue on what's going on in the field.
The real problem arises when you get a bunch on college hires in, train them, and then they leave for ariata and Cisco. It's only a matter of time.
