I don't let the question rattle me. I do some research to work out what the market rate is for the skills and in the geographic area. Based on that I work out what I would be happy with and then add 15-20%. That gives me a buffer for negotiating. If the potential employer baulks and wants to pay much less, I think it is best if we don't get more involved. I actually prefer it when the employee goes first. It shows your confidence and anchors the perception of your value. Taking a job for less than what you would be happy with is an immediate recipe for dissatisfaction. That is a very bad way to start a job.
