i have 20 years of experience and probably 100k lines of code across 40 repos and i have found no way around the leetcode BS so i have decided to no longer apply for anything and focus on my business.
I am in the same boat. I have been casually looking for a new job (while still employed) and found that even companies that say they don't do Leetcode interviews still ask questions that have no direct relevancy to the job, i.e. they test very specific known puzzle solving algorithms (even though they don't call this an algo/data structure interview). Yes, sure, I would be able to brush up those skills again (1-2 months of my free time?..) and become sharper at puzzles, but it just feels so forced.
I've decided to start my own business next year cause I don't want to go through all the leetcode bs too.
