Since you've already attended the selection process and have been assigned a course, it is a bit late for this thread.
It seems you've already made up your mind.
Coming from India, you will feel right at home in Dubai, although the costs of living are significantly higher and increasing rapidly. The company's admin structure, policies, bureaucracy and user interface are also very typical of the region and will be a frustration to only those coming from the West.
The A330 fleet is used mostly on Middle East turnarounds during the day, and India and Pakistan turnarounds during the night. Expect to fly around 600-700 hours a year, although with only 7-8 days off a month.
I would estimate that you could see the left seat again around the middle to late part of next decade.
Good luck with your decision.
