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.

- 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.
