Best wishes. Try not to dwell on it, which will be impossible if you're anything like me. You can't be objective about how the interview went. You probably did better than you think you did. Your story reminded me of my nephew and his wife. He took a job as a principal at a small school, mainly because his son was enrolled and it really helped out with his child care situation. He clashed with the administration and had a miserable school year. He has now moved on and is much happier.
