My first advice would be to make sure that you're preparing for what is required for your interview. It's easy to get into a rabbit hole of things you think you should learn, but that they're never going to ask you. A lot of companies ask for leetcode types of question, so I'd say it's always a good starting point. It's also quite fun to solve problems. I would get the subscription and start with the most frequently asked easy problems.

Leetcode questions were never brought up in the interviews I've had for the time being. There were the kind of questions I've mentioned in the OP and some code exercises.
