An interview isn't just about responding to the prospective school district's questions; it is an opportunity for you to impress the panel with examples of your foresight regarding the position they are offering. By asking questions, you can also determine if the fit is right, it shows interest in the position, and helps to develop rapport. If you feel comfortable, and the interviewer seems amenable, you may ask questions at appropriate times throughout the interview. Once you have been in the interview for a few minutes, you will start to get a feel for your comfort level in this regard. If you don't ask questions during the interview, you will most likely be given the chance to do so at the end of the interview ... be sure to take advantage of this great opportunity!
