One interesting thing though is that from a market perspective, it still ends up making sense for our org (ML research lab). There are simply so many applicants, that we can afford to pass on anyone. All the candidates hired tend to still be excellent on all other fronts AND they can do these quizzes. And it does result in some hires not being the most credentialed ones with the longest CVs but the ones who outperformed during the interview for whatever reasons.
So..I can see it makes sense for the most prestigious orgs, but I still hate it, and I especially do not see why startups who are struggling to hire feel the need to copy this when they clearly do not have the same options.
Another thing that really irritates me when people in hiring committees actually pretend passing them means something about candidates' innate skill. Like, I get it, these are the rules we made up, but do we have to pretend they are that meaningful?
