I was once interviewed for a maternity cover job. There were five candidates, of whom four were female. No surprise that the one man got the job. I guess they didn't want another pregnancy!
In an interview for a full time post in a Roman Catholic school, I was asked how many children I had and how I would manage child-care. I turned to the LEA rep and said that this was not an admissable line of questioning. The interview continued on different lines, but I did not get the job.
I saw another advert for a modern languages teacher. I rang up in advance and I asked which languages were essential as it wasn't clear in the advert. I informed them that I was not qualified to teach German. They told me to come anyway. In the interview they said I would have to include some German and I could just prepare the lessons the night before, as I had done it to A level. I withdrew my application and did not get my expenses paid.
At another interview for temporary work I was informed that I might have to cover boys' PE. I declined to do so, but I got the job, as they were really in need of my main subject, French.
I had five temporary jobs in five years, thanks to moving around. After the fifth, I got a job in a wonderful school and stayed there for over twenty years until I retired.
