If you're the CIA, wouldn't you want to plant employees, or 'hire' employees at major firms like this? I guess I assume they do already. Probably each major corporation has 10-50+ employees getting kick backs from the government.
They do, according to Jonna Mendez, but those placed don’t collect a company salary, only a government salary. This causes some contention since they are paid far less than salaried employees and get no equity, so it leads to high turnover
The US intelligence agencies would have a hard time planting employees in US firms while remaining within the bounds of FISA. They certainly have assets inside major Chinese firms though, of course.
