If you do well, it's also possible to negotiate once you are already employed. You'll probably be more valuable to the company after a year, since you'll know how things work, and chances are good that your alternatives will have improved. I've always brought it up in a positive way ("I think I've been contributing significant value and would like to find a way for my compensation to reflect that"), but the managers understand the subtext ("now that I have a year's experience here, other companies are calling me at home.")

Success will depend on the company, but it can work.
