Weird thing. I am not even a developer and I felt the urge to try it. My point is: doesn't this give incentive to not-that-good developers who might "just in case" pass it and get $1,000? Therefore increasing noise, which is one of the worst things to deal with in hiring?
If I had to plan a bogus hiring strategy that a spy would implement on a competitor and f*ck it up, this is what I would have thought!
