Pretty sure the OP meant that only $500K+ per head FANG employees are capable of writing quality software. To be fair, you can't write any other software at FNG (don't know about A): you won't be allowed to check it in. Some people leave due to not being able to pass the readability review. But FANG employment is not a prerequisite. I have personally hired something like 20 engineers of varying seniority and within a month or two, they were cranking out impeccable work.
