I applied online. The process took 1 week. I interviewed at Aon (Chicago, IL) in May 2021
Interview
Relatively average. It is exactly what you would expect out of an internship interview. What you do, your education, why you want to be at AON, etc. Everyone seems very interested in just hearing about your experience.
The interviewers were very friendly. They made you feel very welcome, and gave a great description of what it is like working there, as well as introducing you to some colleagues you might be working with,
Three different interviews with three different people. The last one included a presentation that you had to give. Asked very typical questions. A lot of prep for presentation. Took a little over two hours.
