It seems like a moot point since there are already too many people who can clear leetcode hard than there are available positions that require it.
It’s like scoring over 2 standard deviations on an IQ test, great, but by definition millions of people can do that.
Edit: I’ve heard HFT firms are now moving to doing it on paper in person to prevent any kind of cheating for their interviews, which would make it a better signal.
Yes,that is better.
From my own experience, LeetCode does indeed enhance one's logical thinking and coding skills. I believe this is the reason why FAG has always tested algorithm and data structure skills in interviews over the years.
