As mathattack has correctly pointed out in a comment an hour ago, this is a parable (a made-up story). The huge salary by that day's standards should make that clear. But the unnamed author makes his hiring methods look stupid, because he should be doing a work-sample test[1] before hiring for such an expensive contract. If he doesn't know what the worker will actually do, he shouldn't put so much money on the line.…
I'd probably be more expecting a Belbin or Myers-Briggs questionnaire to be required, than a work-sample test, to have my suitability tested for certain roles, despite the established effectiveness of various methods.
Great post btw, in the link.
