Wongwai 09
From what I have heard from others, Dragonair has already recruited sufficient number of candidates so you probably will not receive any thing from them (i hope this is not true but I have submitted nearly 2 months by now but I have heard nothing from them)
For CX - If this is your first time to apply CX CPP, you should be able to hear something in about a week or 2 weeks maximum. Hope that helps and good luck!
