I'm looking for a job and this is one of the companies on my list. And just like you don't know yet whether you want me to work here, I don't know yet whether I want to work here either. Convince me.

Well ... "I will sleep with you if you hire me." doesn't sound like a response from a spouse. At least not the spouse of the interviewing person. Which means that at least in the short run the interviewers sex life might get a lot better. Especially if the interviewer is a programmer :-}

I wouldn't consider it a good answer though. At least unless you are interviewing someone to become nothing more than a coffee-cooking secretary.
