It's interesting to see how things have change. Granted, my sample size is 1 for negotiating with Meta a few years ago. In that, I had competing offers, but let the recruiter know up front that I wouldn't share exact details other than company and level. The initial offer from Meta was greater than my asking, and after asking for more to get closer to parity with other offers, they went above that number as well.

Of course, that market looked nothing like this one.
