I applied online. The process took 2 months. I interviewed at AIG (London, England) in Feb 2017
Interview
CV/cover letter, tests, online video interview, assessment day. Assessment day was 2 interviews and a risk group assessment where you work as a team through a project, then present it for 5 minutes as a team. The interviewers were really friendly and helpful. Be sure to treat the interview as a 2-way conversation; ask questions at the end
