Highgate School interview questions

Had 2 face to face interviews at the school. Both interviews were very long and detailed particularly the second one where I was given a tour of the school, introduced to several people, then given a test before having yet another long and detailed interview. Well turns out the whole thing was a waste of my time because someone just called me a couple of days later to say that the role is going to be changed and re advertised. No apologies, no email or anything thanking me for my time and effort. Nothing. Just this is the decision and we wanted you to know, bye. If the interviews were online, I would t have been upset but I had to basically arrange and pay for childcare twice in one week in order for me to go to the school to attend the interviews. Poor experience and poorly handled!
