A history graduate who had built up over £20,000 of debts since leaving university has turned himself into a walking advertisement. David Rowe, who said he had sent out hundreds of CVs and offered to work for free, could not find himself a job . After a bet with his father he decided to pace around London's Fleet Street area with a sandwich board emblazoned with: "Job wanted - history graduate - interview me". His efforts have led to one offer of a job from a London recruitment firm.
