Your Window of Opportunity

 
Your best window of opportunity to negotiate a compensation package is after they say "We want YOU!" and before you say yes.

Once the hiring manager is through interviewing and has decided you are the one for the job, he or she really doesn't want to go back to the drawing table.  This is the time to negotiate your package.  Once you've signed on the dotted line, your bargaining power is greatly diminished if not gone!

And remember, you can't get what you don't ask for!
