Do you have a teaching experience?
My friend, remember, you have a variety of teaching skills as a nursery teacher. In spites of your degrees, you must have a loving &caring attitude towards your students as the age group of these children is more demanding than the grown ups...

teaching nursery children is a very sensitive task...
So one should be extremely professional...

You could be asked some basic knowledge questions, your aptitude, your stamina, your devotion, your special teaching techniques.

They could ask you how to handle a specific situation in the classroom?
