First: an initial assessment taken online testing what type of thinker you are (I believe) Second: Phone Interview, basic behavioral questions Third: On campus interview, more behavioral questions. One person interviewed for 30 minutes then another person came in and interviewed me for another 30 mins. Final Rounds: They changed the way they did it this year. There was a tour of the Aon center and you were to prepare a 3 min presentation. You gave the presentation to a panel of talent acquisition and the other candidates. They eventually talked about who they wanted to move forward, and at the end of the day split us in half. Half of us moved on to present for the CEO while the other half was put in a room to have round robin conversations about other potential direct hire positions.

Amazing interview process. four rounds. They really try to get to know the real you. The last interview was a "super day" where they had candidates create a presentation, and have a panel ask questions. Gave you the opportunity to tour the office, taste test their products, learn from previous trainees.
