It is interesting that the form of cheating would be defeated with in person interviews / testing.
I do wonder if you cheat your way into Amazon wouldn’t you get caught being bad on the job after you are hired?
Or are we talking about people who are generally qualified but look better than others because they cheated?
Sure, they cheated to get in, but then once in they found out it wasn't that hard to stay and get promoted.
I actually had this issue at my current job where we hired someone who seemed great and who did really well on his interview exercises but then once he started working... well, it was pretty obvious he did not know what he was doing at all. So he was let go straight away. There was no way he could cheat his way to stick it out for longer than a month.
Bingo. The cheaters will get the job because they will look better than similarly qualified candidates.
