A job offer letter looks like good news you just sign and return. But it’s the one moment you have the most leverage you’ll ever have with that employer — and the details buried in it decide your real pay, your flexibility, and what happens if things go wrong. Read it like a contract, because it is one. Here’s how.
Never accept on the phone
When they call with the offer, be warm and say “I’m excited — can you send the full details in writing so I can review?” Everything real should be on paper. Enthusiasm is free; a verbal yes locks you in before you’ve seen the numbers.
Separate salary from total compensation
The big number is base salary, but your real package includes bonus (and whether it’s guaranteed or “target”), equity, 401(k) match, health insurance (and the monthly premium you pay), and PTO. A $75k job with a 6% match and full-premium health can beat an $80k job with neither. Add it up before you compare offers.
Decode the bonus language
“Up to a 15% annual bonus” is not a 15% bonus — it’s a ceiling that depends on company and personal performance, and it’s often prorated in year one. Ask: what did people at my level actually receive last year? Is any part guaranteed? A “target” bonus is a hope; a “guaranteed” or “signing” bonus is money.
Watch for a clawback on signing bonuses: many require you to repay the full amount if you leave within a year (sometimes two). If you might not stay, that “bonus” is really a loan. Read exactly when it vests.
Check the start date, title, and who you report to
Confirm the exact job title, start date, work location (and whether remote/hybrid is in writing or just promised), and your manager. “We’re mostly remote” said in an interview means nothing if the letter says on-site. If flexibility matters to you, get it written into the offer.
Read the clauses that follow you after you leave
Look for a non-compete, non-solicit, or broad IP-assignment clause. A non-compete can limit where you work next (enforceability varies a lot by state — some ban them outright). An IP clause that claims anything you create, even on your own time, is worth questioning. These are normal to negotiate before signing and nearly impossible to change after.
Most US offers say “at-will,” meaning either side can end employment anytime. That’s standard — but it also means a verbal promise of “you’ll be here for years” carries no weight. Don’t turn down another opportunity based on spoken assurances.
Negotiate once, professionally, before you sign
You almost never get a better shot at more money than right now. Pick your top one or two asks — base salary, signing bonus, start date, or remote days — and make them together in one polite email: “Thank you, I’m excited to join. Based on my experience and the market, could we get the base to $X? I’m ready to sign at that number.” The worst outcome is they say no and you’re where you started.
Ask about raises and reviews before you join
Your starting salary sets the base every future raise is calculated from, so the path after you join matters almost as much as the offer itself. Before signing, it’s fair to ask: How often are performance reviews? When is the first one? How are raises and promotions typically decided? A company that gives clear answers is showing you a real career ladder; one that gets vague is telling you something too. If the base is lower than you hoped but the offer is otherwise strong, you can also ask for an early six-month review tied to a raise — get that written into the letter, not just agreed in conversation. Knowing the raise cycle turns a flat starting number into a plan.
Get every change in writing
If they agree to a higher salary, extra PTO, or remote days on a call, ask for a revised offer letter reflecting it. A promise that isn’t in the signed document effectively doesn’t exist once you start. This isn’t distrust — it’s how professionals close a deal.
Get the offer in writing, add up the whole package (not just base), and decode the bonus and any clawback, non-compete, or at-will language before you sign. Make one clean negotiation ask — this is peak leverage. Then get every agreed change into a revised letter. Sign the document, not the promises.
Quick questions
Will negotiating make them rescind the offer?
Almost never, if you’re polite and reasonable. They chose you and don’t want to restart hiring. A respectful ask for market-rate pay is expected — rescinding over it is a huge red flag about the employer anyway.
How long can I take to decide?
Asking for a few days to review is completely normal. If they pressure you to sign within hours, that itself is worth noticing. A simple “Could I have until Friday to review?” is standard.
What’s the difference between exempt and non-exempt?
Non-exempt employees must be paid overtime past 40 hours a week; exempt (usually salaried) generally aren’t. Know which you are — an “exempt” title can mean lots of unpaid extra hours.
Should I mention a competing offer?
If you genuinely have one, yes — it’s your strongest leverage. Be honest and specific; don’t bluff, because a called bluff destroys your credibility.
