Hey Chanty, congtats on getting to the final interview. I had my final interview mid-august and got the call 16 days later that I had been accepted, but some of the people at my interview still haven't heard back.
So don't worry about them not calling you yet. Some of the recruitment team back in dubai are faster than others. Also, they don't have a certain number of people that they take from the final interview.... if someone is good enough they will take them.
I start on october 10th, only 2 weeks away! I wish you the best of luck and hope to see you in Dubai soon
