I applied in-person. The process took 12 months. I interviewed at Islamic Development Bank (Jeddah) in Oct 2010
Interview
The whole process have been significantly improved in terms of actually receiving a response yet remains very long still. You will get contacted 2-3 months later for an interview, which now includes various online tests, and subsequently if short-listed an on-site interview with a panel of interviewers. Generally recruitment can take 6 months
