Generally convincing people to do what they don't want to do.
I think this is pretty despicable requirement. Convincing people "to do what they don't want to" generally would involve deception. Even when 'successful' in the short term such sales ultimately are counter productive. Convincing someone that "now is the time to do what they already want to do", would be a far better approach than the "make the sale at all costs" approach.
I bet the "convince people to do what they don't want" line coupled with the movie marathoning emphasis of the job posting would lead to some over the top interviews:
Applicant: So, Jim, what I am saying is that I am ready to get out there and convert some of those SOB's and get them to sign on the line that is dotted! Gimme some leads and I'll close those corkscrewers right now! Let's attack Jim!
Interviewer: Heh, heh. You must have read the old job posting, we changed it after we got some flak from the media. Anyway, your enthusiasm is noted, but there is a process that we follow, references to be check, testing etc. Watch your email, we will be in touch with the next steps.
Applicant: Screw that! Not convinced, eh? You don't think I know this is a test? Listen, I can go out there tonight, and make $15,000. Can you? I could sell cameras off the street corner to the blind! With no audio! Mobotix! In downtown Shenzhen!
Interviewer: Somebody get me security, we got another Glen Garry nut!
