How to start salary negotiation
Look up salary information for similar positions.
Before you develop your own range, you should have a general idea of the going rate in the industry.
Make sure you have a full understanding of the particular job being offered, including the exact responsibilities and expectations for someone in that role.
That will help you evaluate what the position is worth in other firms. Different companies may call similar positions by different names, so if you don't have an understanding of the full job description you won't know which other jobs compare with the one you've been offered.
