A job offer arrives sounding close to final, and most people respond to it that way, accepting quickly or pushing back only on the number. That treats the offer as a decision to react to rather than a conversation still in progress. Getting more information before you respond usually matters more than how forcefully you push on any single number.
Why the instinct to respond quickly works against you
The moment an offer lands, the pressure is to answer, gratefully, promptly, decisively. That pressure works against you specifically because it cuts short the part of the process where you would actually learn what else is negotiable, timing, title, start date, equity, remote flexibility, none of which show up in the first email.
Chris Voss, a former lead FBI international kidnapping negotiator, developed a set of tactical moves for exactly this problem, extending the moment before you have to commit to a position, so you have more to work with when you do. They translate directly to a job offer conversation, which is lower stakes but the same basic shape, one side has more information than the other.
Mirroring, said plainly
The first move is repeating the last few words of what the other person just said, back to them, as a question. If a recruiter says the offer reflects what the role is budgeted for, repeating budgeted for back, as a question, tends to produce more detail than asking directly why the number is what it is. It keeps them elaborating without you committing to anything.
Labeling what you are sensing
The second move is naming the emotion or pressure you sense in the conversation, without judging it. Something like noticing it sounds like there is a real deadline on this. Said plainly, this tends to surface information that would otherwise stay unspoken, because naming it invites the other person to confirm or correct it rather than leaving it implied.
Asking what and how, never why
The third move is calibrated questions, opened with what or how rather than why, which tends to read as accusatory even when it is not meant that way. A question like how would this work if the start date moved by a month invites the other side to help solve your problem, rather than putting them on the defensive.
Where to start
Before you respond to your next offer, write down one thing you actually want to know more about, timing, flexibility, what is fixed and what is not, and prepare one mirrored question and one calibrated question around it.
Use them in your next real exchange, over email or on a call, before you say anything about your own position.
Knowing which specific thing to push on, given your actual offer and how much room you actually have to negotiate, is something only you can judge from inside the situation. What this gives you is a way to get more information before you have to decide what that push should be.
There is a specific way to sequence all three of these moves in one real conversation so they read as careful rather than evasive, and it is worth working through before your next offer lands.
