Invited for interview and was the only candidate. After a book scrutiny and lesson observation, I was told that I would not be interviewed as the lesson was "not to our standard". The 2 reasons given did not constitute a poor lesson on the whole. I was under the impression that an interview lesson was part of a selection process, and not just make or break. My letter of application had stated clearly that I wished to move to a new age range so could clearly adapt my teaching style, given my 20 years of relevant experience. Is this situation normal? Should one always expect an interview?
