That's strategically sound. If you omit the "no" and soften the "never" by substituting "don't", you achieve the same thing without jeopardising the flow of interaction.

Just say "I don't share that." in a good natured, confident smiling tone. Then be absolutely silent and wait for them to continue the conversation.

If they rephrase their enquiry, don't revisit your statement, which has already been clearly delivered and doesn't require repeating. Instead, take the opportunity to move the conversation along:

"What salary and conditions are you offering for this position?"
