I've come across at least one person that felt into that description, in the past. He was most definitely un-hireable - if anyone spent a second studying his (fake) past experience or his (non-existing) technical ability/interest on learning - had no idea what he was doing, but somehow managed to not just join a "big corp", but stay under the radar for years until he got promoted to a management position (where I believe he is today).

yeah I can fizzbuzz
