leetcode is just a skill like any other skill. If you understand the data structures / algos behind it (which are mostly CS stuff you learn in college), given enough time, you should be able to solve the problems. It's okay if instead of doing a medium problem in 15 minutes it takes you 4 hours at first. Start solving and make a habit of doing 1-2 problems per day. In no time you're going to learn that the problems are doable and the time it takes to do a problem will go down a lot. When you can do an easy in 10 minutes and a medium in 15-20 min you're ready. I have rarely seen hard questions in an interview. Also the more senior you are, the more the emphasis is going to be on system design and behavioural. Yes, it's stupid. It is what it is. You know what is going to happen, you prepare for it, you get the job.
