Rasgas interview answer

Hello,
I've been contacted by Rasgas further my application for an engineering position.
I know that the recruitment process in Qatar is quite long but I'm wondering why I did not receive any reply regarding their final decision neither from Rasgas nor my agent. It's now 3 weeks that I passed the interview which was (from my own judgment) quite positive.
Is it the normal process to wait 3 weeks or more to get a answer? The fact that I have no feedback means that the answer will be negative? Do I have a chance to receive an offer from them in the coming days?
Thank you all for highlighting me.
Cheers.
Nobody to help me??
Thanks
