The interviewer(s) has no power over your life, not presenting your case to a judge here. You didn't have the job when you woke up this morning, you may or may not have it when you go to bed. You can't lose anything, only gain.

Some advice that has stuck with me came from Andrew Carnegie's How to Win Friends and Influence People. Yeah, modern sensibilities take that old-school title all wrong. It's a book about the author's quest to better understand social interactions and document his findings for future people feeling as lost as he did, thereby making himself a better person. It's the only book I'd recommend to anyone. Give it a spin.

When faced with potentially world shattering change, and an interview is not that, I force myself to take a breath and ask, "What happens if the very worst consequence I can imagine comes true?" Go nuts here, get dark, what's the worst you can imagine?

The answer is invariably, "I'll soldier on, somehow survive." Not like I'm going to blow my brains out, whatever happens. And you won't either.

"Will I get this job?" is nothing compared to the many difficulties life throws up. I'm on the hunt now, after leaving an employer that treats their employees like gold. In fact, I'm on severance pay ATM, but running out fast. What if I have to go back to an office everyday? What if I only end up getting paid half what I was making? Fuck, what if I end up selling boiled peanuts on a corner downtown to make our mortgage? Well, I won't die, that's for sure.

The second thing I'd say, talk to the interviewer just as you would a friend of a friend, an acquaintance that maybe has an opportunity for you. They're not kings, and you're not their subject. Approaching them as an equal makes one hell of a difference, exudes sincerity, and that lets them see you as your really are. And isn't that what you both want?
