Applied on the website and was called few weeks later for a case study. The case was a 90 minute preparation followed by a presentation to 2 Willis employees. They called again 1 week later for a verbal/logic test followed by a role-play case, lunch with some analysts and associates, followed by an interview with 2 Willis members. Next I was called for another round of interviews (1:1) with 2 of the C-level directors.
