Ya I had the stress question too, and we went over it for about 10 minutes.
I didn't say I would take a nap, but I did say that that I generally leave situations where the stress is building to the point where I might act irrationally.
This is an equally negative response to the question "how do you react to stress?".
When further pressed and asked "how would you deal with stress when confronted with a hostile induvidual while on patrol in Afghanistan", I recovered somewhat by saying that I would take a few deep breaths and consider my training and respond to the situation as that training would dictate, that I would not simply be looking for the easiest way out. I also added that I was not a hothead and that in unavoidable stressful circumstances I do not ever react with anger or violence, that in every day life I am always able to analyse the situation and determine what the best course of action is in consideration of my own feelings and also those of the induvidual I am dealing with, and can usually defuse a situation from escalating further. Also that I do not run away from conflict when it does become neccessary to be there to prevent violence from happening to my friends or other induviduals who are expressing passivity.
I was greeted with the response "good answer".
When discussing my competitiveness, the recruiting told me my strong points and also my weaknesses, and this wasn't commented on one way or another, so I think I recovered well enough.
For others facing this question, I would suggest going into the interview thinking specificaly about how you think you would react to the kind of stress you might face while on tour, and not the kind of stress you face from your parents, or some drunk violent guy at the bar. Personally, I know I deal with stress way better while I'm representing my workplace than when I'm out drinking with my buddies, but that was the kind of stress that lept to mind during the interview, hence the need for a recovery answer.
