I'm going to somehow contradict some of the comments and agree with others. Every time I changed jobs in my career, whenever I grinded Leetcode I ended up in a better position (more and better job offers) than when I didn't. That being said there are diminishing returns. You don't need to solve hundreds of problems, possibly a few dozens should be enough to significantly change your odds. However I agree with others that you are putting way too many hours. The other funny thing is that I have always, at least in part, done Leetcode during working hours. This might be an option for you to a) cut down working hours and b) actually use hours towards your goal. In any event good luck.
