You're joking, right? The question is jarring because it's asked in an interview, for many, after applying to dozens if not hundreds of companies. Not getting too attached to any applications since the majority never even see a rejection email in response, many more will send the rejection months later, and the 1 in a few dozen applications will get to a phone call with a recruiter.
So yes, the reason I want to work "here" is because "here" is the company that responded.
