Hi Louis,
you can look around the Web for more information. There is an
ATC Web Ring where you will be able to get a variety of ATC information world-wide. You will also find a number of ATC simulators, such as
ATC simulator.
There is a shortage of controllers in Europe, estimated at around 10-15%, and unlikley to be resolved in the next 5 years - so there's goning to be vacancies for some time to come. The job can be very demanding, but also very satisfying
Good luck
