He got in because no one cared about anything other than someone willing to push through boring contract design work for low AF pay. He seems to still believe his lying(skill?) is what got him the job. It sort of was in the sense they wanted someone young dumb delusional and enthusiastic to work for next to nothing on what was essentially boring boilerplate work. In a system that even at the time he could see was a disaster to work in. Then used him as a negotiating tool to lay off other decently paid workers after he "proved" that what they did to him could be done. He calls them "expert manipulators" but there is nothing expert here, this is ham-fisted pointed haired boss 101.
TL;DR the company wanted a useful idiot with enthusiasm to push through a broken system to do a mind numbing job for next to no pay. The author still doesn't seem to get this.
