Has anyone completed the English exam and face-toface interview?

I have an upcoming face-to-face interview in Atlanta for a teaching position in the UAE. I was informed that there would be an English exam before the interview. Has anyone completed this exam? If so, how was it? Is there any information about what will be covered on the exam? Also, how was the interview process? I have been looking forward to this opportunity, and I want to as prepared as possible. Any suggestions would be appreciated.
