How do you negotiate a higher salary during a job offer?

When you receive an offer, don't accept immediately. Thank them and ask for time to consider it. Research market rates for the role using sites like Glassdoor, LinkedIn, or Bureau of Labor Statistics data so you know what a fair range looks like. When you counter, be specific and confident. Say something like "Based on my experience and market research, I was expecting something closer to X. Is there flexibility there?" Always anchor higher than your target since employers expect negotiation. If they can't move on base salary, negotiate other things like signing bonuses, extra vacation days, remote work flexibility, or earlier performance reviews. Stay professional and collaborative throughout, framing it as finding a mutual fit rather than a confrontation.
