How to Negotiate Your Offer
Practical steps that move the number without damaging the relationship.
Start your ask above the median. You'll rarely be offered more than you ask, so anchor high and let the employer negotiate you down.
Stronger approach:
- Start your ask above the median
- You'll rarely be offered more than you ask, so anchor high and let the employer negotiate you down
Say 'market data puts this role at $X–$Y' — not 'I was hoping for more'. External benchmarks are harder to argue against than personal expectations.

When base is stuck, negotiate equity vesting schedule, signing bonus, or accelerated refresh grants. Total comp has more levers than base alone.

Ask for 48 hours to review. This creates time to counter and signals that you take offers seriously — not that you are uncertain.
