Hopefully we can at least agree that those questions are limited in effectiveness, and often have no actual relation to how good an engineer is. It varies of course.

Sometimes, they seem more like a secret handshake you need to memorize to get into the boys club than actually useful engineering. Who hasn't had to revise some of these before applying for a job 3 years out of college?

What it does do is effectively exclude applicants who didn't study CS, or who haven't heard of and memorized "cracking the coding interview".

Assuming `fake CS questions == good engineer` is a huge mistake, but one i keep getting downvoted for everytime i mention it. Most rebuttals are usually something like "it's the best system we have", something i find unsatisfying.
