As a lead engineer at a non-tech company as least as big as many of the FAANG companies I am responsible for things that make 8 and 9 figures annually (mobile), but I never had an interview anything like this here at all, because I was hired based on personal reputation at a previous employer. I bet I would fail miserably at these kinds of interviews because I would not prepare in any way; I know what it takes to ship things in all sorts of ridiculous circumstances, with too few people and enormous continuous changes under challenges that you would never see in a big tech company. I am not sure there is fair way to tell from an interview what I am capable of but my present org knows what I can do and counts on me doing it every time.

I wonder how many people are missed in interviews who would make a big contribution to an employer but are lost in the interview process. Often skills needed for shipping quality applications are likely not visible if people only focus on raw programming ability. Maybe it's simply too hard to identify in interview form so everyone just looks at how you write code.
