Admittedly, I got my job nearly 20 years ago, but it seemed a lot simpler to get a teaching job then in terms of the interview process.
I had different interviews at different schools, but none of them required me to teach a demonstration lesson. Or to talk to the pupil council. Or anything beyond answering interview questions really. I had one where I had to play the piano in front of all the governors (including 2 pieces that I'd never seen before) but that was because it was for a music subject-leader post.
It seems a lot more....involved these days.
