Vatican "Devil-Caster-Outer"

Did you know the Vatican had an official exorcist? I didn't either, until I read this item:

Adolf Hitler and Russian leader Stalin were possessed by the Devil, the Vatican's chief exorcist has claimed.

Father Gabriele Amorth who is Pope Benedict XVI's 'caster out of demons' made his comments during an interview with Vatican Radio.

Father Amorth said: "Of course the Devil exists and he can not only possess a single person but also groups and entire populations.

"I am convinced that the Nazis were all possessed. All you have to do is think about what Hitler - and Stalin did. Almost certainly they were possessed by the Devil.

"You can tell by their behaviour and their actions, from the horrors they committed and the atrocities that were committed on their orders. That's why we need to defend society from demons."

He doesn't care much for Harry Potter, either.

How do you get the job of official exorcist? What's the interview like? Do they bring in a possessed person and you have to cast out the demon within a specified time period (kind of like a typing test for a secretary)?

Now I'm curious.
