By first stage do you mean sending in your CV and being sent the standard assessment invite?
If thats the case PM me as I'm at that stage,
Have you received the DLR info? For an experienced captain I'm sure there are better ways of finding suitable candidates rather than than asking , for example, what causes weather or what the eustachian tube does? Their train set I guess.
Seems they are going to build up a pool of acceptable pilots to commence in 2017. Will they then do the CAAC medical for candidates, who knows. Will there be Chinese trainers, as they are presumably be operating with a Chinese AOC?
