To get the interview, you just gotta have some years of experience, some side projects, and that's about it. If you went to a top tier school or something like that, you don't even need the years of experience. Getting an interview at those companies is the easy part, pretty much everyone I went to college with got an interview with one of those companies before graduating (and I didn't go to some super known ivy league college, it was just a pretty good public school in Georgia). The issue was that most people didn't pass those interviews.
To pass the interview, read up on systems design, read up on algorithms, practice some leetcode/hackerrank/etc., and you are good to go. All of those resources can be easily obtained for free. There is no secret or trick to any of that.
It’s not easy, and you may need to actually go to the place where those jobs are. But each of those companies will hire thousands of people at those compensation level in the next year. And the people they hire were in no way exceptional (or different to you) before they started down the path to getting where they are now.
There’s no reason you can’t be one of them.
