Congratulations!
I don't know anything about the present recruitment but I would suggest to remind them regularly and ,shall I say firmly, of your existence, because from personal experience, the notion of "holding pool" leaves much to be desired at Cityjet.
I was selected in November 2000 and was supposed to start my training on BAe146 in January 2001. Then, it was postponed until April. Then...nothing! They simply forgot my existence despite regular contacts, due to lack of continuity in their HR department.
My words of advice is to e-mail,call them or pay a visit to their nice Sword offices on a regular basis, to monitor the progress of the "holding pool".
By the way, the only person I know who got in from my selection has just been promoted Captain. They're getting more aircraft. So it is a good company to work for, with real career prospects once you're...in!
All the best
