No. Sorry Al, you are wrong. I agree with interview nerves. Everybody has them. Fine. What you are describing is 'Key Account Management', or channel sales. Sales Executives are trained to close. Hard. Not long term relationships, just qualification, and closing. You only care about revenue streams if:
a. You're self employed;
b. You're a Sales Director;
c. You're a Channel Sales Exec;
d. You're a Key Account Manager;
e. You're a corporate Account Manager.
And please do not start going down the double glazing route. It is incredibly stereotypical, rude, and just down right offensive.
And I think you'll find that as far as the interviewer is concerned, they won't give a damn about whether the end user is turned off by arrogance. An arrogant salesman who can turn negatives will have a higher hit rate that a nervous salesman every single time. Full stop.
