I applied online. The process took 1 day. I interviewed at Aon (Hong Kong) in Apr 2016
Interview
The process lasted for 1.5 - 2 hours and included a 2-min self-introduction and 30 mins group discussion on a case study with 20 mins preparation. When I was doing my self-introduction, the staff was not listening to what I said compared to other candidates in which this was very rude to me. Lastly, they briefly introduced the programme as well as the company and you can ask any question at the end.
The process took 2 months. I interviewed at Aon (Hong Kong)
