What are the unwritten rules you must learn to get a top job? Hashi Mohamed came to the UK aged nine, as an unaccompanied child refugee, with hardly any English. His academic achievements at school were far from stellar. Yet he now works as a barrister - and so is a member of one of the elite professions that have traditionally been very difficult for people from poor backgrounds to crack. So how did he do it? In a personal take on social mobility, we meet his mentors. These are the people who gave him a few lucky breaks and showed him how to fit in to a world he could barely imagine. But how many people can follow that path? And why should they have to?
