I was asked about how I would managing behaviour, what current issues do I know of that are relevant in education (spoke of the money that is being put into sport over the next 5 yrs), what do I know about a Teachers day to day life, how I would manage my workload etc. I referred a lot to what I have observed in the classroom. Go onto to the BBC Education site and have a a look at recent issues. Sure you will be fine, the person who interviewed me made me feel very comfortable. Good luck!
