I'm in the fortunate position of having two companies ready to make me an offer. The two firms compete with each other regularly over talent, so I told both recruiters I would share information about my other offers to try to give myself a better position to negotiate from.
Unfortunately, both groups got around to preparing offers at nearly the same time, so now both recruiters are withholding information about the offers they're prepared to make, waiting for the other to make a move so they'll have the upper hand in salary / benefits negotiation.
I've gently pushed both of them to share more information about the offers they've promised, but so far neither has responded, presumably because they don't want to set the price that negotiation will start at. How should I break the deadlock without weakening my negotiating position?
