Neither leetcode nor homebrewed are what we want anyway. But homebrewed is IMO worse because it could be a weird format and people have issues with surprises during technical interviews, least of all anxiety. And when there's a bunch of different flavors and formats, candidates either prepare for them all or accept that they won't do well at some formats and forgo those jobs.

IME candidates are spooked way more by leetcode than homebrewed tests that mimic the job they do every day.

I'd estimate (from browsing graduate boards) it's probably among the top 5 most hated aspects of the industry. #1 for many - because it's so anxiety inducing.

Your experience must be different than mine then, which, it's a large field so it's totally possible. Dunno, it'd be great to not have to repeat any kind of technical test, regardless of the format preferred.
