Not top 50 people but I know someone from our group of teenagers/early-twenty-agers friends who just lied to get hired for a tech company in Belgium. He never went to uni but most of his friends did, so he knew a bit the who's who / hang out with these people and he faked a resume, lied (written down) about having a diploma in economics.
He started climbing the corporate ladder in that company (I think it was HP but I don't recall all the details of this story, it was a long time ago) then after something like 10 years, he started getting cocky and thought that now he could move to another company, boasting 10 years at the previous company and this or that title he had now.
Bad luck for him: the company he applied to did a background check and realized he had no diploma (I don't know how they found out? Is that public information? But they found out anyway).
They didn't just not hire him: they warned his current employer, the one he was working for since 10 years, that he applied lying about having a diploma.
He was fired on the spot [1].
I don't know if there's any moral to this but if you lie and your lie works, you better then keep a low profile for a very long time.
[1] Some are going to ask: "If he was good at his job, why fire him?"*. To me the answer is simple: you don't want a relationship (personal or with an employer/employee) based on a lie to begin with.
