I work at FAANG (not Amazon) and have worked for similar companies. I was rejected by multiple top tier hedge funds after 1-2 tech rounds, after getting a mid tier hedge fund a few years ago. I interviewed with multiple then pre-IPO companies that have since IPO'd. They all asked Leetcode Hard problems on the phone screen even. My original FAANG + hedge fund interviews from a few years ago were not even quite as difficult, just some dynamic programming questions and tricky recursion, mostly Leetcode medium with some hards thrown in occasionally.

I also got an offer from a crypto exchange which is a household name, but they claimed they switched to non-negotiable offers and wouldn't even match my current TC. I had to walk.

Now wondering if this is just some game that companies are playing to either make themselves seem more selective or show "growth" through hiring / headcount to make investors happy. The interviewers also seem less enthusiastic about selling their companies to me, and more like they already made up their minds that they do not like me. One kept asking me more and more questions to cause us to run out of time so that I wouldn't be able to code.

The questions I'm being thrown at all are ridiculous in difficulty now, and the interviews feel like they are designed for me to fail. Who can code a segment tree in 20 minutes? I ended up completing this one, and it wasn't even the hardest question I was asked. I even had a recruiter ask me to prepare for their company's interview by doing TopCoder Div 1 500 problems. That's absurd (IOI difficulty level). There are people in Eastern European countries who do nothing but train for these competitive programming problems with coaches and all since secondary school.

I suppose I will just remain in my relatively cushy FAANG job. Despite having very little time to prepare, being employed while interviewing can be a good thing, after all.
