For a period I was heavily recruited by google. Their recruiters tried a great many variations of attempts to trick me into interviewing for a job. It seems weird that they would do this, because pretty soon, it would become obvious that it was a job interview and nothing more. Maybe there are a lot of talented engineers out there who are doing startups but aren't really committed to them and google manages via the fame of its name and wearing them down to convince them to give up and become employees.
I agree with this article's characterization of it as a scam, as they are pretending to be something they are not. This is manipulative and dishonest. What I experienced was less heinous but had the same elements- misrepresentation, name dropping, attempts at emotional manipulation with tone and timing (the first call being so dead, then enthusiastic in the second- very "HR recruiter", not corp dev.)
Worse, once I'd eventually figure out what was going on, and put one of them off of me, a few weeks later another would show up, with another variation.
