Leetcode deselected too many good experienced candidates, which is really who I prefer to hire. I have hired good leetcode juniors that did not improve and are no longer working in software.
Did you select candidates with easy / medium / or hard LeetCode problems? Honestly, without studying, people need to be top 5% of candidates to solve hard problems. You can find real algorithms stars with those problems, but you will also pass on a large percentage of "good enough" candidates who can do a medium problem with a bit of hinting.
