When gaming it is just passing by studying, a repeatable process that anyone (with a CS degree) can do, just means the interview process is quite well designed.

The interview process is a test of endurance, not intelligence. And it should be exactly that, since software engineering is mostly an exercise of endurance and focus.

Every time a friend of mine QQs about failing a FANG interview, I give them the study prescription that worked for me. The reaction is always the same: they don't do it. If you can't get past these interviews, you probably won't make it past a year in these high performance companies anyways. Because you actually have to exhibit the same work ethic that interview studying requires.
