Yes - but for some reason, there's this extreme (irrational?) fear that imposers might have coasted through Uni., and you get these infamous blogs and articles stating that "comp. sci graduates can't code anymore! candidate failed fizzbuzz!", and everyone seems to have their own anecdote about that one co-worker that couldn't code themselves out of a wet paper bag. It seems like we're in a situation where companies would rather pass on 10 competent devs, rather than hire 1 incompetent dev. Personally, I think most of the above boils down to bias. You only remember the best and the worst coders you meet in your life, as far as work quality goes. And those are outliers. Coding interviews are stressing, so you can end up with competent candidates completely blocking due to the stress, and thus failing trivial problems. Anecdotes seem to be the gold standard, as far as evidence goes.
