A, but there's a catch! I've asked for a company's range many times, and they have yet another non-answer answer: "we don't have a firm range in mind, we're confident compensation won't be an issue for a top candidate".

It's a game of chicken. The best counter I have is "what is the top of your range if we have a perfect fit?", but even that doesn't always work.

At this point, I'm sick of games. If a company refuses to disclose a salary range and/or insists on getting me to quote a number, I lead with $2X0 and see what happens. 80+% of companies aren't willing to hit that high, and the other 20% have been more interesting roles at higher quality companies.
