But the advice of this article to "make sure you have other offers" is pretty much impossible to pull off in practice. If you have offers from startups, they're generally going to be for less than Meta is offering in the first place. And if you have better offers from the rest of "AANG", then the whole point is you can just take one of them. But this article starts with the premise that they're not doing much hiring right now, so I don't know how you're supposed to get those offers.
And all of this ignores the fact that coordinating the timing of offers, so that you have an open offer from another company, when Meta makes you their offer, is virtually impossible. You have no idea, when you start interviewing with another company, if they'll make you an offer in 3 days or 3 weeks or 2 months. And they generally give short deadlines as well.
So I don't really get what this article is trying to achieve. What Facebook is doing is pretty standard for corporations in a powerful hiring position, and the advice to try to counter it is nearly impossible to pull off. This is just how capitalism and labor markets go.
But, this article is definitely useful so people know how the process is working right now.
