Was going to disagree but ended up coming around to the argument. I guess the difference is at a certain point preparation turns into a wasteful arms race, it’s not just a reasonable amount of effort put into your next gig but too much effort on things that don’t really represent real day to day / reality. Not sure where the line is, but there is definitely waste and it definitely favors those with spare time.

Does seem like there is a growing movement to explicitly not do leetcode style reviews at many places which is good.
