I guess I've heard of another type of gaming of requirements: the H1B thing. The story here goes that they need to demonstrate they looked for someone with the same skills as somebody hired under an H1B. So they post job listings that are extremely specific to the person they hired, that no one can match.

No idea if that's true. I heard it claimed by many. I guess it sounds kinda implausible for a large company, they would need to create possibly thousands of fake job listings.
