Qatar correspondance is very slow when compare to other countries. Pls try to be patience as much then only you will get positive reply. If you are in vist really worrie abt days ends but no results of interviews. Your field of scope is very less compare to UAE. UAE is Marketing country lot of opertunity. Qatar is valued for Techincal Skill Persons. I hope my reply will give positive face.
All the best Friend
Hope to see you in Good Job in Qatar
