4. Don't give a number at all. If you are interested in Company X, and you've gone far enough in the process to know they are interested in you, tell the recruiter that you would be interested in seeing a competitive offer from Company X, or something along those lines. At the end of the day, the best negotiating leverage you have is that if Company X actually does want to hire you, at some point they have to commit to an offer. You don't. You can always walk away and go talk to someone else.
