I agree, however you do end up participating in it, you get used to it, and you bring it with you. That's the fear anyways. I think it's a little bit true. Facebook has similarly nutty PIP ("PSC") culture, and you see it from ex-Facebook folks who run other organizations once they leave.

I have seen recruiters red-flag FB/IG managers, depending on why they're leaving FB/IG for this reason. Engineers less so but it definitely comes up in the interview process. It comes up the other way too, when I interview - particularly senior - FB engineers, their first question is "tell me about your PSC culture."
