The salary negotiation process starts sooner than you think
Understand your options
Be calm and polite at the negotiation
1) Be calm - You know that the employer knows of your unique heroic experiences. These facts will speak much louder for you than any verbal tactic you use during the negotiation. In fact, by this point, the employer probably already made up their mind how much they are willing to negotiate for you. Staying calm and inscrutable will be strong allies for you.
2) Be polite - the person on the other end of the negotiating table can do a lot for you or to hurt your total package. Politeness goes a long way and you are dealing with a human being. You've showcased your talents, you reviewed your options, and you understand your leverage. At this point, being polite but firm will only reinforce all those great qualities you are bringing to the table.
3) Take your time - no matter how weak or tempting the offer, thank the employer for "putting together a thorough package" and let him/her know that you will need some time to review the offer carefully. Advise him/her you will provide a response after a set duration - typically, no longer than one week.
