It doesn't matter. I just expect an intelligent answer that reflects understanding of the circumstances in which you, as a candidate, are in. I also look for signs that you might be bad fit, a risk, a fraud or a waste of time.

We all know that most people don't exactly love their jobs. I think it is fine. Just because I do doesn't mean everybody has to. You can still be productive without being workaholic and abandoning your friends and family and promising eternal love and devotion to your company.

But I am also obligated to find people that will actually help the project and bring value to the company and try to find a compromise between seeking perfection and filling positions.

On that end I need to somehow judge, from a very limited amount of information during a very broken process if it is worth to continue with somebody.

If you can't find a semi-convincing answer to a question you should have expected to be asked, there is probably some problem with you. Do I really want to spend effort trying to figure it out?
