I taught a faux lesson to the director. After waiting almost an hour, she took me to a small room and I was going to explain some vocabulary terms but I tripped on my way walking to the board. She laughed so hard that she hired me on the spot and said the students would like me.

It was surprisingly comprehensive. They started with a very simple grammar and usage test and then a teaching demo. The other teachers demoing didn't seem to know much about teaching or grammar, but one of them was hired, along with me. I think the point of it was mostly to see how you engaged the "student" audience and less about your teaching know-how.
