I trust they were really competent, but it's a bit depressing that these competent people will need to go through the leetcode rituals and 5-10 interviews to get a new job at Meta, Netflix, AWS or adjacent companies. That's actually the point of the original post; you are never judged by your (years of) experience or even your past companies, only by the results of a test from a random person/company.

I am glad that you mentioned Google. At this point, their interview process is legendary. It is so good that many other companies have tried to copy it.
