This question is different from person to person. For myself, I would respond, "I would first let them know that as long as they treat me with respect then they will get respect in return. I would also set boundaries and let them know what would be acceptable. If they continued to be hostile, I would separate myself from them and then report to management."
The answer was simple to understand but thorough: I grew up in Silicon Valley and have studied its history to have a clear view of the future, my sales, finance, and legal backgrounds gave me a skill set perfect for the position, and I explained my work ethic. What impressed them was the work ethic and knowledge of the company - I had prepared past their expectations and if I could continue to work that way I'd fit right in.
Yes. Keep in mind most companies sales goals are considered proprietary and cannot be demonstrated. One could still prove by commission check stubs. In retrospect, I don't think that a "no" would be detrimental. Agreeing to find an alternative on the spot shows integrity and an ability to think quickly to find solutions.
