> Then there are take-home timed challenges on systems like hackerrank / leetcode etc, which are horrible in terms of accessibility and access. Not to mention that they are a pass/fail, and focus purely on speed, not quality.

This does not mirror my experience. Many times that I have interviewed with hackerrank/leetcode questions, I wasn't able to get all of the test cases to pass. After time was up, I explained my solution to the interviewer and talked about the failing test cases. Sometimes I passed the interview; and other times not. It was not binary: Imperfect means 100% fail.
