Salary negotiation is all about information asymmetry; typically the company holds all the cards and the candidate none. Not sure any article could help with that in any way.
This is only partially true. Sure the company has a lot of cards but they are playing a different game. They are Hikaru playing 12 blitz chess games at once, and potential employees are offering something, else they're not negotiating they're just working out the terms of their slavery.
Not exactly. Some candidates outright lie about competing offers or existing compensation. Less unscrupulous tactics are to give TC figures based on the peak of the stock price performance, which isn't technically a lie - you just forgot to cite the most up-to-date price.
