One step at a time:
1. Take the interview
2. Take the second interview
3. Recieve the letter saying you have been succesful, but there is not presently a postion
4. Receive the offer of a start date. NOW think about the ban.
5. Take the job. The ban is immoral, stupid, counterprodcutive, unfair, poorly thought out, not supported by many CX pilots.
(Ignore step 5 if you like...but follow 1-4)
All training courses for this year are full anyway, so the ban may never become an issue for you.
Its a great place to work! Good Luck!
