Any company still using LeetCode at all during interviews is signaling that either they are run like a frat house, or are so dim/indifferent that they're unwittingly cargo-culting one.
I'm the type to talk with HR about when the company could do something better, and some of them appreciate it.
(Most recent was when a company was starting each Monday morning with a miserable cross-hemisphere all-hands meeting videoconf... that sucked the life out of the recharged energy people came back from the weekend with, for the potentially rewarding work we were doing. The company improved.)
