Its also not even inefficient. Jet pilot courses reject people for arbitrary reasons. Because they have a limited number of jets, and a surfeit of applicants. At some point you 'weed out' even good applicants, if you have more than enough of them.
Surely you could use a random number generator to do this?
That would be nice, because it wouldn't leave rejected candidates thinking they did something wrong. The whims of a panel of interviewers isn't necessarily different from an rng anyway.
I generally support this- as a FAANG employee I sometimes think an RNG would be a much better signal than a lot of our interview voodoo. At least then we wouldn't be hiring unlucky people!
