I applied online, I did not have a referral. I was invited to do a video interview ( Did not know it would be a website recording me and no live person ) An internal recruiter for Aon called me and asked about my experience, job change etc. Two weeks later I had a phone interview with a managing director, then the next week I had an in person interview with another person ( This was an average to difficult interview as I knew this was the last interview ). I had two pending offers with other companies, so I called the managing director and explained I had other offers, I was then told I had the job and they asked when I could start.
