I applied online. The process took 2 months. I interviewed at Aon (London, England) in Oct 2012
Interview
First to enter an online application with a CV and a cover letter. If successful, then you would be invited to an online Situational Judgment Test (SJT) that should take around 45 minutes. Then there will also be a first-round, second-round interview and as assessment centre based in London.
