Hi Mrs Thaskala, I recently interviewed at a school and was thankfully successful. It was a full day involving a tour of the school, three panel interviews including a student panel, and a demonstration lesson observed by the the head and deputy head of department.
Each panel had slightly different questions.
Panel 1: Academic - Deputy head, academic, HOD, deputy HOD. First were questions around my demonstration lesson - basically asking me to analyse what had gone well, what I would do differently next time, how I would amend it if I had students with special needs in the class, how I would amend it if I could teach it over a series of lessons instead. They had read my application and had specific questions about that - e.g. around the merits or not of planning all lessons of work in a unit or planning day by day/week by week. They asked my approach to differentiation and how I ensured all students were keeping up. They asked why I taught and how it compared to other careers from my CV.
The student panel had questions on what I would do if I a student disclosed an allegation of bullying, why I went into teaching, the year groups I liked teaching best etc, what I liked about their school compared to others I had taught at, from first impressions. They were all A level students.
The third panel was with the Head Teacher and the Head of HR. They asked why I went into teaching, how I would handle specific situations - e.g. being a form tutor to a group of disgruntled GCSE boys, what I believed were the essential skills of a form tutor, what I believed were the most important personal skills a teacher could focus on with their students. What self worth meant to me and how to teach that. They asked how I had been enriched personally by working with children and what I had learned about myself. They asked about my approach to classroom management.
I hope that is somewhat useful. Try to imagine that everyone you come into contact with from your first approach to the school to the person who gives you to school tour etc will feed into the selection process somehow. I think it important to write to the school after to thank them for their time regardless of who they choose, to have all of the documents they ask you to bring in order etc etc etc.
To prepare for my lesson I went through common questions and prepared demonstration answers and scenarios to demonstrate my answers that could be amended to suit the specific slant of the question. I had questions for each panel specific to their interest - e.g. questions on their staff evaluation process to the head of HR, questions on progression and school approaches to behaviour to the head teacher, questions on syllabus and the merits of coursework or exam route only to HOD etc.
Wishing you lots of luck. Its a gruelling day but also great if you are prepared and show yourself off to the best of your ability. It can help you to realise your true value to the profession.
