Sr account executive from a leading advertising in india having 3 years of experience, What are my chances of getting a jobdubai advertising?

I think you would definitely increase your chances by checking your spelling first. Attention to details is a must in our industry!

Dear Rizwan ....... Good Day! Well you asked a very futuristic question. Its totally depends how effectively will you promote your talent to the dubai avertising industry. Dubai has a lot of tendency to expand in terms of business but you know the competition here is very high. 

SO if you are really serious to relocate yourself to DUBAI, make a portfolio of your talent, Experience and Achievements and mail it to a few top HR consultants. 

The response from them will take atleast a couple of months but it will definitely let you decide your future.

Good Luck.

* And remember one thing, IF you are determined enough to get something you will overcome all your weaknesses (Including your spelling. So dont take the negative comments seriously)

Rizawan to be honest it'llbea bit tricky answer this because im not that familiar withDubai's mkt.
