We once had a young teacher, who had to pass his own entrance exam for a permanent position. He was to be tested by teaching us, while a senior teacher sitting in the back judges him. A week before his test, this young teacher then goes through everything that was supposed to happen in that class with us, right down to the questions he'd ask and the answers a specific pupil was supposed to give. At the end of it, he promised us a keg of beer if he passed (Germany, younger pupils would maybe have gotten sweets). He passed with flying colours, after which the senior teacher asked discreetely when we intended to drink that beer, because he wanted to attend. Obviously stuff like this was completely normal and expected.
