My roommate works at Meta and from how he describes the culture to me it seems quite intense and competitive already. I can't imagine what "turning up the heat" even more would imply.
That's what I thought too, but then in my first PSC as a manager when I was there I was added to a spreadsheet called "<org name> stack rank", where we had to rank everyone rated as Meets All, because we were 3 people short of our quota for <= Meets Most
