If you spend an entire man year in senior productivity to vet a single employee, perhaps that's the problem then?
I have often seen this problem explained (for example by Paul Graham) that a bad employee is a negative value, they make bad commits and stupid decisions that net out as a massive negative for the company. But it seems very counterproductive to try to solve this problem at the selection moment using stupid proxies such as leetcode memorization, instead of during the trial period, when the employee is, you know, interacting with your company.
