Basic analytic exercise 15-minute presentation 30-minute interview Overall, improvisation and randomness seem to be the normal process. Invites are sent 48 hours exactly before the assessment centre, whereas you are asked to tell 48 hours in advance at least whether you can come or not. There is no phone screening nor any personality/IQ test, it seems you are invited to the assessment centre on a random basis solely. The analytic exercise is quite simple. Other companies would ask you a business case.Here, you are only asked to look at a 4-column excel spreadsheet and to answer 3 questions using pivot tables. During the presentation, you deliver your answer to a 3- interviewer audience. I found out that these interviewers do not know whether the must ask you questions after the presentation. I wanted to ask questions regarding the role and the company, but they answered me they were not allowed to answer before the interview. Thus, we just sat for 20 minutes, waiting for the interview. The interview is about behavioural questions. Unfortunately, once you have answered these questions, there is no time left for you to ask questions. Moreover, interviewers do not seem to be bothered about what you know about the company, the role, what your career aspirations are. I felt I had much more information googling it than having this interview. Overall, the process is far too light and too basic to enable Willis to select the best candidates. It is more likely they like you or they don't. You don't need to be good for this role, and if you are, you might not find this environment right for you. Improvisation seems to be the rule at Willis. When you come from overseas, it makes it a very expensive but useless trip.
