The point about stereotype threat is valid, although it also means that we're unable to get any insight into a major axis of interview performance.
I think what we have here is an attempt to imply, consciously or not, a causal link between interview success and previous/current employment. But without drilling into the other factors underlying their success, we get a lot of noise and not enough signal. Couple that with the continued mythologizing of FAANG greatness, and you get an article that perpetuates two of the more toxic notions in tech: FAANG is the top of a pyramid and talent is concentrated in a handful of companies. Neither are true, and neither are probably your intent, but that's how this reads.
