Very short interview. They contact me one day after I submitted my application online, and arranged a phone interview three days after that. They just asked about my age, how did I know their school, where is my current location, what is my current job, what is my marital status and if I will be travelling alone, when I am available, what is the preferred location for working with their school network, how many years of teaching experience do I have, what subjects I taught, what subjects I want to teach, what is my salary expectations, and that's all.
They didn't ask any question related to the job, just general questions. Maybe this is the first interview they do, I don't know if they will contact me again.
