Was there a choice on your application for enroute, approach or tower? I'm pretty sure you guys will all be doing enroute or at least that is the case with our recruitment wave. I think they've found that as enroute is easier to simulate accurately, the success rate for trainees in the field is higher than the other disciplines. Also, I think I'd be pretty annoyed if I was sitting in enroute for years waiting for a Tower or Approach position to pop up and then some rookie comes in and fills it straight out of training.
I could be wrong, they may have changed the recruitment process again. Just letting you know what those about to start were informed.
All the best for the testing.
