What you're describing are the people making $1M+, you basically need to have had amazing luck of being in the right place at the right time and being involved in projects that turned out to be massively successful and grew quickly. That's how you get those Director or Sr Staff/Principal titles at FAANG.
To make $250k+, honestly you just need to be able to ace a random assortment of Leetcode level Hard problems under pressure. Which is actually a very tangible and unbiased skill. To get in the door of that interview in the first place, now that can be a challenge without the right kind of experience. But it's not impossible to gather that right kind of experience, without an Ivy League education or advanced degree, by gaining experience on the job for several years at a lower tier tech company or startup.
And then for some lucky few, a $200-$300k mid-level engineer salary can grow into a $1M+ salary without any promotions, e.g. every mid-level and above engineer who joined Snapchat two years ago. That's the real holy grail.
