Learn their 'Lingo'
Learn about the company and spit their language back at them. In school they told you not to paraphrase, in interviewing it is the way to go. Read up on them. Check their mission and/ or value statement. Take their words and say them in a different way. You will seem like you fit right in, and way worth the upper limit of what they can offer you.
Look like You are Worth the Investment
Dress well. Smell good. Believe that you are worth it. If they sense that you have confidence they will want you and feel that you are worth whatever they have to pay you to get you. Well, more like whatever they can afford to pay you to get you.
Negotiate Creatively
If they won’t budge on the money, make them move on other things- like not making you work a full year for your two weeks of vacation or letting you leave a little earlier on a Friday every few weeks. There are lots of things that you can ask for. The worst that can happen is they say no. Salary negotiations are not fun and they are not easy. Be prepared. Knowing you stuff may make all the difference between getting a great salary and kicking yourself for not getting enough.
