Also, to clarify, I used to end my interviews with TWO questions: (1) if you had 10 years to live, what would you do? [wait for answer] (2) if you had 10 years to live, would you take this job?
The things I was assessing in these questions were candor, intellectual honesty, and passion. Sure, it would be great if people authentically were passionate about taking the job if they had ten years to live. That was a tiny minority of responses.
The only "wrong" answer to these question was when someone would answer YES to the second question after clearly answering something completely different to the first one. For example, if someone would say travel the world to #1 and yes to #2.
The reason why this measured candor was because if someone could tell me to my face during an interview they wouldn't take this job, then I knew they would tell me to my face when something was broken in the company after I hired them. I was looking for the exact opposite of what this thread implies I was looking for. I didn't want ass kissers. I wanted truth tellers.
