This feels really confused. You know the leetcode answers are just during the interview, right? Once you get the job, it's a job that involves solving real problems.
Spending a few months doing some leetcode revision to pass some interviews that could personally yields me hundreds of thousands, potentially millions, of dollars, is a very acceptable trade-off. Many people accept that because the risk/effort/reward ratio is very worthwhile.
I've worked in two FAANG companies and the level of talent and skills is phenomenal, an order of magnitude over anywhere else I've ever worked. They all played the game, and continue to play the game, and receive the rewards for doing so.
Choosing not to participate because you dislike the process isn't going to change the hiring process.
Sounds like there are about 2-300,000 points …
