I loved this article and it's honestly life changing. It takes a bit of time to realize how much you're in the driver seat as a candidate. Especially with competing offers, there's no way you should be accepting an offer with less (unless its a small startup) if you have another offering more.
A 5 minute call that can increase net worth by large multipliers is probably worth preparing for. With the help of https://levels.fyi and other salary tools out there, it's incredible how open a lot of this information is. You just need to put in a bit of time and effort.
Without leverage these negotiating techniques are empty bluff. I mean, they could help to get a 5k/year pay bump, but they won't get you from 150k to 750k. The really important ingredient is stakes, insider knowledge, network of high rank friends who help you behind the scenes. But once you have that, the negotiating skills will come naturally: even if you aren't as fluent in business-talk like the author, even if what you say sounds clumsy, the fluent and experienced negotiator on the other side of the table will quickly notice that lazy tricks don't work on you, that you see his bluff and most importantly that you actually have other options. In my experience, in many times my firm negotiating position ended up with offer being withdrawn (from reputable, not FANG, but very well known firms).
