yeah I just grunt and snarl when I google and find a forum post from 2007. I wish there were an easy way to filter by date. I have faith in your problem solving abilities. I'm 35 and have a CS degree. The only time I've needed to know Big-O or how sorting algos worked was in college and during interviews. I've literally never been in a situation where the code functionally worked, but ran too slowly because of an inefficient algorithm (and this is with 13 years as a C++ developer). As for your situation, I suspect many shops would turn you down because you didn't rattle back the answer from memory. But the concern isn't that you aren't smart enough, it's that you're "old" and cost too much. The kid who memorized leetcode can be bought cheaply and discarded easily if it comes to light that he/she can't figure out how to solve a tech bug. If you "follow the money", these interviews could be seen as purely "cheap-but-comptetent people-filters". Because if an old programmer tried to sue them for age discrimination, they could point to leetcode as evidence that all the tests were administered "fairly".
