I applied online. The process took 5 weeks. I interviewed at Aon (New York, NY) in Feb 2015
Interview
Had to complete a 10-question video interview (5 essay questions, 5 video) within 48 hours of receipt. Then had four 30-minute phone interviews. Was told by interviewers that I would hear back anytime between one week and one month; I heard back in about four days and was offered a different role.
