your ability to solve leetcode problems has absolutely nothing to do with your ability as a computer scientist or software engineer; most of my friends haven't ever used leetcode (or even heard of it?) and have become CS PhD students, CS professsors, technical founders, open source maintainers reaching millions of people, and software engineers at assort big tech cos. The culture surrounding leetcode and gaming tech jobs is really toxic and you shouldn't let yourself get sucked into it.
