Many forms won’t let you complete them if you leave spaces blank. Hellmann advises putting in $1, $10 or $100, “anything to show you’re not listing your real salary.” Hellmann insists it’s not fair to discuss compensation before you’ve had a real job interview.
Great advice. You should never reveal your current salary when negotiating your new one. It makes no difference what you were paid previously, unless they are trying to pay you less.
