I have changed employers a lot, never asked for much on average (proportionally to the risk let's say), so my salary grew up a lot without difficult negotiations. (And -- yes, it did happen to me that I was offered more than I asked for... it is very, very far from being good thing for your future in the new company.) One point to keep in mind. In my personal experience, big companies are frequently behave well when hiring for regular tech jobs -- they won't offer stellar salaries, but will not try to squeeze you dry from the start either (will try to get you to what they believe is median for your qualifications). And usually will let you understand this during salary negotiation, so you kind of have less reason to conceal your present figure. However, as you salary grows, many of them will not be adjusting the grade in the hiring process (and of course never afterwards, except for big promotions). So when negotiating, once you got the amount from them, ask where it lies on the range for the grade you will be given. Make sure there is a margin for growth. If there is not -- beware, it might be very hard for you to be raised afterwards, however excellent your results might be.
