In regards to the Tosh quote, how many people at FAANG companies are using most of these tested skills in their day-to-day jobs, ever? This isn't about testing useful domain knowledge (except for the handful of people working on core algorithmic problems). To a point these questions are an intelligence test but I see them mostly as a form of gatekeeping, seeing how many hoops people will jump through to land a job there. Most decent coders COULD pick up the knowledge to pass but not all of them want to, need to or are willing to grind through the test prep stuff just for the chance. And filtering for THAT has value because people won't grind through the process are less likely to hack it being smaller cogs in these behomoths. I think the biggest value of the leetcode process is to rub off competent programmers who need to feel like their code is meaningful. Obviously many people produce meaningful code at FAANG corps, but working at a huge company means your code has a decent chance of never see the light of day or get chopped after 2 years, or be thrown out in some new broad initiative... It is an effective filter for finding people who don't need external motivation to keep plugging on ahead. It is an important distinction because those types will likely flame out or start to wilt after a few projects of coding into the void.
