keep calm and carry on.
Interviews are vastly different between schools, between primary and secondary, and thenfaith etc introduces another area of differences. make sure you know what the last Ofsted report said (look online), what the school's mission statement or ethos is (these are a lie in most cases, but worth knowing if you want a job). other than that, provided you know your tradecraft - planning, assessment, safeguarding, organisation, dealing with @rsey parents, and definitely never clip 'em upside the head, then they can ask you anything, you'e got the answers.
best of luck.
