Not sure how they're doing number wise against target. If, as posted above, 1050ish people have been interviewed then they will probably still not have more than half their requirement filled. I thought the pass rate through the procedure was somewhat less than than 50%. You can do the sums. If recruits are hanging around prior to training it's likely to be down to a lack of training slots, 6 months from joining to final line check was a good average for guys joining about 2 years ago.
I was also contacted very recently about by an agency looking for type rated 777 F/Os for a middle eastern carrier. It wasn't EK nor EY. Hmmmmmm.
