I interviewed with 3 companies recently, and all had some kind of coding test, although not all of them were Leetcode-style problems. But I did practise on Leetcode before, and it was useful for passing the interviews.

However, in my experience those kinds of problems don't make you a better developer. They are almost the opposite of what you do day to day as a developer.

I've written more about it here: https://henrikwarne.com/2021/04/19/recruiting-software-devel...
