The offer email says you have until Friday. It's Tuesday. You're relieved, excited, and also aware of a narrowing window in which you're supposed to somehow figure out what's negotiable, what isn't, and whether asking for anything at all puts the whole thing at risk. Nobody explained the rules of this specific moment, and you don't get a second attempt at it.
Negotiation Skills 101 covers the underlying principles that apply here — BATNA, interests versus positions — but a job offer window is its own particular situation: short, one-time, and higher-leverage than almost any other negotiation you'll have with this company. If you're reading this after you've already accepted, that's a different, narrower situation with its own answer.
What should you actually negotiate before accepting a job offer, beyond salary?
Almost everything in the offer is a variable, not just the number at the top. Salary tends to get all the attention because it's the most visible line item, but start date, signing bonus, title, remote or hybrid arrangement, vacation time, equity, and the timing of your first performance review are all frequently negotiable, and some of them are easier to move than salary itself.
Start date matters more than people expect — a later start gives you room to close out a current job properly and costs the company very little to grant. Title can matter for reasons beyond ego: a more senior title on paper can affect your leverage in every negotiation you have for years afterward. Signing bonus is often more flexible than base salary precisely because it's a one-time cost rather than a recurring one.
Equity, if it's part of the package, is worth understanding in detail rather than accepting at face value — the number of shares or units matters far less than the vesting schedule, the current valuation, and how the company's equity has actually performed. A large-sounding equity grant tied to a four-year cliff and an uncertain valuation is a very different offer than the same headline number with different terms attached.
This is the one moment where you have full information about your alternatives and the company has already decided it wants you. That combination doesn't repeat itself once you've started the job.
How long do you realistically have to decide?
Almost always longer than the deadline in the offer letter suggests. A stated deadline is a default, not a hard rule, and asking for a reasonable extension rarely costs you anything with a company that genuinely wants you.
A few days to a week is a completely normal ask for most roles. The exception is roles with a genuinely tight internal timeline. Even then, asking for a short, specific extension rather than an open-ended one tends to be granted.
What do you say if you need more time before responding?
Ask directly and specifically, rather than going quiet or stalling without explanation. Silence reads as disinterest; a clear, bounded request for time reads as someone taking the decision seriously.
"Thank you so much for the offer — I'm genuinely excited about this. I'd like a few days to review everything carefully. Would it be possible to get back to you by [specific date]?"
Naming a specific date, rather than asking for "some time," makes the request easy to say yes to, because you've done the work of bounding it for them.
Can negotiating actually cost you the offer?
In the overwhelming majority of cases, no — not if the ask is reasonable and delivered respectfully. Offers get pulled over aggressive ultimatums, dishonest claims about competing offers, or last-minute demands well outside market norms, not over a candidate asking a company to reconsider one or two specific terms.
A company that rescinds an offer over a single reasonable, respectfully worded request was very rarely a safe place to work in the first place.
What questions should you ask that have nothing to do with salary?
Ask about the things that are hard to reverse once you've started — team structure, manager expectations, and how success is actually measured — since these shape your day-to-day experience far more than the number on the offer letter.
A few worth asking directly: Who will you report to, and has that person been in the role long? What does success look like in the first six months, concretely? What's the team's current size and any planned changes to it? None of these questions are aggressive. They're the kind of due diligence a company respects.
How do you handle multiple offers or a tight deadline?
Be transparent about the existence of a competing timeline without turning it into a bidding war, and use the real deadline pressure as a reason to ask for a decision, not as a threat.
"I have another offer with a deadline of [date] — is there any way to accelerate your process, or could you share where things stand?"
If you're choosing between two live offers, resist the instinct to only compare the salary lines. Line up the full picture side by side — role scope, growth trajectory, team, benefits, and the base number.
What to do next
The days between an offer and your answer are a real negotiation window, not just a pause before a decision you've already made. Ask for the time you actually need, look past the top-line number to everything else that's movable, and treat reasonable questions as due diligence rather than risk.

What questions should you ask beyond salary?
Who you'll report to and how long they've been in the role, what success looks like in six months, and the team's size and structure. These shape daily life more than the number on the offer letter.
