I know that at one point they were experiencing 1500 applications a day for 100-150 jobs, however I expect a lot of them are Non-UK Licence holders. If you're Airbus rated, you'll be of interest, especially a trainer. There is approx 30 command upgrades in the hold pool, all for winter course, only for 73 and 75. If you're looking for a DEC gig on either of those fleets, I wouldn't hold your breath. Airbus however, they'll be very interested as there has been no delays in the 321 order.
I know that assessments have taken / are taking place and some job offers have already gone out. I only know of NTR/TR 737 FOs being interviewed at the moment.
