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."

I don't think most people at the IC/engineering level would choose that culture, but once they're in and inundated into that environment, how many are going to propagate it out of habit? That's the risk.

I've seen recruiters red flag Uber engineers as possibly sexist (and to a lesser extent racist).

I think that is pretty much all big companies at this point
