Actually, no. A common tactic is to take out a classified ad in a low-circulation newspaper. The ad is, of course, poorly written and looks like a scam. (Generally accepted practice is to run it in two news papers one day per week for two weeks) This is to reduce the chances of an American applying to the position. After all, what professional actually reads the classified ads? None that I can think of. And writing the ad poorly and like a scam is designed to dissuade any professional from calling about the job even if they happened to somehow stumble across it.
Nevertheless, sometimes an American will respond to the ad, which is where the "qualifications" section comes in. The company will publish a laundry list of qualifications that no one has. sometimes they'll demand more years of experience with a particular piece of software than the piece of software has been in existence for. (e.g. 10 years experience with Windows 8). More frequently, they'll just chain together arbitrary pieces of software that are totally unrelated. This allows them to trash the applications of any Americans. The foreign workers, however, know to put this huge list on their resumes, even if they don't actually have the experience. Importantly, there is no requirement for the company to verify the experience of any applicant. However, if an American attempts this same tactic, they'll exercise their *option* to call employers and check references to prove that the American is lying.
