> Some of the best people I worked with that brought real value would never pass big tech leetcode interview...

FAANGs don't do leetcode. They may ask about data structures knowledge, but even their coding interviews are aimed at evaluating stuff like system design, write readable code, be coachable, and even soft skills.

I interviewed at Microsoft and I got multiple questions lifted straight from leetcode word for word. Some easy and some hard DP questions.

Google and Netflix had hard questions as well, but they were all novel questions not on leetcode/hackerrank. However, CS algorithms 101 were fundamental to both.

This is incorrect, they absolutely do Leetcode and Leetcode is full of questions cribbed from FAANGs.
