I live in Western Europe too and I never heard of this Leetcode thing until today. I make almost the lower end of the scale you gave (or I would, adjusted for working 40 hours, but I actually chose to work just 32), and I could be making a lot more if I had been a little less self-critical and somewhat more persistent with a career. I'm not a developer though, I'm an Admin type (or precisely, currently a IT Systems Architect) with loads of experience, but no formal education. My successful job interviews have been a guy in shorts and flip-flops asking me for two minutes about the products and tech I know, in 2008 (okay, that company turned out to be desperate), and a one hour sitting with an HR and a technical guy, during which I was asked to solve the puniest problem in shell, ca. 2015 (I literally wrote down one line of shell and a pipe to awk on a whiteboard). Though I did also work for Amazon way before this, too, the companies I describe here were medium or large, but not high profile types like Google or Microsoft. Also, I can well imagine though that the situation is somewhat more formal for developers.
