It doesn't matter if you think that leetcode doesn't make a difference, if the company asks for it, you need to be ready to jump in and do it. In case you never studied this before, you need to start from zero and read books about it, there's plenty of $30 dollars courses that will teach you everything you need to know -- as long as you put the effort into it. Furthermore, Leetcode easy/medium aren't about memorization, most of them they are about knowing algorithms, complexity and stuff that you'd have in an university CS course. If you've read Cormen et al's "Introduction to Algorithms", have done most of exercises and got it down, you'll likely already do well enough if you just practice some to write common algorithms quickly that are frequently used as a part of a solution, like BFS, DFS, stacks etc. There are some medium exercises that are about either some maths or binary arithmetic, those you can even leave it out as it isn't very common to be asked, but it's worth to study them once you are very confident with the basics. I know it's a pain to review it, but if they ask it, you need to be ready to prepare yourself, honestly I wouldn't like to work with somebody that in any small challenge that they have, they'd be coming up with excuses to it and that's a filter that they are using successfully against you so far. "What have you done lately?" - I've been preparing myself to become a developer again, here's a list of things I've done meanwhile: (big list) That's what they want: play the game or keep having the same results that you had before. As you are looking for a job since 2022 you should have been preparing since then, but it's never too late, start to prepare now, go to programming meetups and even pretend to be working in a company of a friend or colleague you met there. There are so many things you can do to fill that gap, you can also just lie, but that isn't something many can do.
