Snap! Fifteen interviews in one round! No job! I think in many schools however good your application letter and lesson is, the bottom line is what matters at the end - money. If they have someone who is a prospective NQT 15 out of 16 times you've had it! (Here's hoping I prove that right!) Good luck - the ball has to get in the net eventually however many NQTS are standing on the goal line to stop it!
