^ If they had you fill the Immigration Form & do your Medicals means
You're Hired! (considering you're Medical Fitness is upto their Standards)
Just wait for them to revert to you, it may take some time but as long as you know you're fit enough, you will be on a CX A330 doing BOM - HKG very soon.
Congratulations
By the way, i called-up Cathay India HR & Personnel, Spoke to a very polite lady who clearly said that CX HKG Team should be handling this directly as they (India) have nothing to do with the process, she was courteous enough to still wish me Luck with my candidacy - I really appreciated that.
So
my wait continues................
