Ive had people show up at onsites that were clearly not the same person I screened over the phone earlier as far back as 2013 at google. It’s real. Just ask any recruiters from well known companies and they’ll tell you. It’s happening to more and more startups too now because it’s gotten easier
I believe you, but again: I haven't experienced anything like this, ever. One of the clearest results we got at Matasano adopting this approach was a drastic reduction in turnover, which is exactly the opposite of what you expect to see if people are scamming their way into jobs they can't do. That's held up (I don't have the before/after comparison, but I do have the industry-wide comparison) over the years afterwards. We hire these people, then we work with them, and they're amazing.
