edit: I never even touched on factors like productivity and its main explanation factors: intelligence and hard work. If I have more intelligence, and I work ultra hard, I should be paid more than you. That's why compensation is mega hetoroscedastic: that is why we have bands and why the bands are so wide and there are outliers. What made me also cringe is the people who are clearly not the "cream of cream" negotiate and get to such places: if the "process" did not exist and they were just interviewed technically for 5-6 rounds they would have flopped and the company would save itself some troubles. My 2 cents.
> they don't even know what zero-mq is
Why does it matter that they've never heard of a specific library? If they're working in a domain which requires something like that, most companies at that scale will either be using it or a similar home-grown alternative, which they'll be familiar with. If they aren't, then what does it matter?
> you only get 1/4 of by definition
Not totally clear what that's supposed to mean but in any case Google & Facebook (along with an increasing number of other tech companies) no longer have a 1-year cliff - your equity starts vesting immediately on a monthly basis after you join; it's significantly de-risked.

What exactly do you think the interview process at these companies is, if not multiple rounds of technical interviews?
