I applied in-person. The process took 4 weeks. I interviewed at CTC Group (Khartoum) in May 2014
Interview
Smooth, with direct questions, basically you need to get your self that interview, weather it's online or going there in person, or best of all graduation program.
HR gives a form to be filled by you, then you continue to the actual interview, make sure that you don't tick the box (I've a family member working here), this will only get you in trouble.
