Qatar Airways Interview Marketing

I was interviewed for a commercial (Marketing) position on 3rd of September at Doha headquarters. The interview was brilliant and I loved meeting the panel as they made the situation really comfortable for me so I managed to give my best and I would like to thank them for their valuable time. I was told that I would be updated on status of my interview within two weeks time and its going to be two weeks this Wednesday. I just want to know how long actually it takes to finalise the result of face to face interviews. In the UK successful candidates notified within a week, so I am wondering what is the response time is likely to be as this is my first ever job interview with a company based in Middle East. Do you think if you haven’t heard within 2 weeks time lag means you are not successful?
