Yeah, I've never understood all of this salary secrecy crap. Just tell them what you want to be paid! If it's way more than they can truly afford, at least you won't waste any more time.
If you know what the market is paying and are comfortable with a particular wage, what the hell does it matter if you're under everyone else?
It sets the dynamic and expectations. Obviously if it's crazy, it also provides an immediate opportunity to correct an unreasonable expectation.
