On your second point, I've seen this in the UK public sector. Because of a commitment to advertise every job that comes up when someone went from temp to permtheir job was re-advertised and they would have to reapply. Imagine competing against someone who was already doing that exact job and had been doing it well for two years. I had an interview like this (as the person already in-post). "Can you give an example where you did X" "Yes, last week - remember you were there and saw me do it." What a waste of everyone's time.
