Why do you want to work here?

A few thoughts about this question:

This is possibly the worst question an interviewer could ask an interviewee. Why do companies always assume that interviewers are dying and ready to work on their companies? Beyond that, this question forces the interviewee to make up some sort of butt-kissing response about how remarkably unique and amazing said-company is before he/she has even finished interviewing there. 

Instead of asking this arrogant question and assuming everyone is dying to work for you, interviewees should tell the interviewer about what (in his/her opinion) makes the company special and sets it apart from other firms.
