Hi jceee
After "the" email, you'll get a call from them and they will ask you to start your medicals and send the scanned copy as soon as possible.
I've done my medical test today and getting my result by next Monday
After you send the medical forms to them I think they will contact you for
the contract and visa and ticket etc.
Good luck on your medicals and everything, hope I'll see you in Abu Dhabi!
