No they don’t.

They waste very large amounts of candidate time on an essay like assignment before you get to talk to someone.

Truth be told they already know from your resume if you’d be worth interviewing. That’s enough , and maybe a OA.

The best process I’ve experienced, was a quick conversion with a few technical questions, then I can start as a contractor. If it works out it works, if it doesn’t that’s ok too.

No need for me to write a long paper, when HR probably took one look at my resume and sent out a rejection.
