I believe LC wasn't a thing back then, or at least not mainstream.
I don't waste my time on LC now. If I get free time, I'd rather work on a personal project or hobby.
Granted, I'm actually thinking of moving into some sort of corporate strategy analyst role since I don't really get to code anymore. The past 2 years has been very little coding or business problem solving. It's mostly been config, infrastructure, prod support, and meetings/paperwork. I'm tired of it. I want to solve problems and build substantial things. I assume I'm rusty when it comes to coding now.
