Also, as a hiring manager, the one way people found themselves with me saying "That's great, go screw" was when it was clear they were playing us comp-wise by lowballing us to get their foot in the door & then raising the bar once the offer came. That's deceptive, and a character flaw I don't want to deal with in an employee.

Now if you mean keep your cards close to the vest and don't reveal your number until after they give theirs, then I agree. That's good negotiating tactics. But it's not always possible. And now we're back to who is in direr straights: is the candidate willing to walk away if the company demands a number & they don't want to give one? Is the company willing to lose a candidate in this situation? Whomever blinks first wins the day on this one.

People always talk about competing offers, but your negotiating power will never be higher than when you literally don't care if you get an offer or not. If I'm perfectly content in my current gig, the only way I'm leaving is for a *serious* upgrade. And it's no skin off my teeth if I walk away from a bad deal.

Sometimes you're desperate for a job and they have you over a barrel, but there's no reason they need to know that.
