Not only does this disincentivize HR from running fake vacancies or stringing multiple candidates on just to keep their options open, but it also solves the problem of unemployed people job-searching effectively working full-time for free. The fact that companies would have to pay to hire workers would mean they try to make the selection as short and effective as possible.
I would say that solving the problem in the way you did makes you well or over qualified, lol.

That guy/gal. You want them, that one, the one with the capacity to think outside of the box, within the specific technical realm of the job.
But, we live in a world run by MBA’s with extremely fragile egos, so, we get insane nonsense instead, where every business process is basically built around making incompetent idiots feel smart.
