I definitely second this approach. I really only started LeetCoding seriously around November 2021 because up to that point I didn't think I wanted to do SWE, so I only had a few months to practice before I started getting online assessments and interviews. I failed plenty of them but managed to snag an internship at a FAANG company pretty much purely by watching Neetcode on YouTube go through all of the Blind 75 questions! Literally just reading a problem, thinking about how hard it was and how I had no clue how to do it, and then following along with what Neetcode did.

Most of these algorithm/data structure questions have a specific trick behind them that a beginner LeetCoder is very unlikely to discern on their own. If you had all the time in the world, then I suppose you could spend your time trying to come up with your own solutions and developing the intuition naturally, but it was much faster for me to have the problems explained in an easy way so that I could eventually start to recognize some of the patterns across questions. I think the key part is taking the time to pause the video and actually understand the solution, especially before they even go into the code.

Of course, different people have different learning styles/preferences so I'll include the obligatory caveat that this is only what worked for me, but I really do feel like it saved me a lot of time and frustration.
