My interview was split into two parts, intelligence and behavioral. Each part was given by a different consultant. During the intelligence interview I was asked to teach my interviewer something new and to estimate the size of a water reservoir that would serve Boston. We discussed my experiences during the behavioral interview. I found both interviewers very easy to talk to.

it was smooth but you need to work hard on your calculations skills, i failed in this part of the case because the calculator is not allowed and i had not familiarize myself with it before the interview but overall it was a good experience
