You may inquire at the initial interview about the salary range for the position. The Actual Negotiation Process Do not negotiate salary until a job offer has been made. Once the job offer is on the table, salary negotiation takes place to determine a salary and benefit package that both sides will be able to live with. It does not have to be an adversarial relation and should be a cordial discussion. The job offer will remain on the table regardless of what you express in the negotiation.
Negotiation involves compromise.
First, determine the need to negotiate. Evaluate any offer which is made. If you've done your research, you will know whether or not it is a fair offer. The more education and experience you have in your field the stronger your negotiating position will be. You will need to draw attention to the transferability of your skills.
