I sent off for the application form (even though I doubt they will accept me because I am epileptic). 1181 Euros for first 11 weeks if you are single and an ex-patriate (i.e. you and me probably, not being Belgian - although being in the EU, the UK might count as a patriate country).
After that it goes up to 1475 for 5 months. After this five months it goes up to 2037 Euros for the rest of the training.
If that is after taxes that isn't too bad considering after training you'll be earning 3700 Euros and eventually 4700 Euros.
They take 30 people a year from all around the world.
