Oliver Wyman Engineering interview questions

I entered the interview with an open mind after hearing different stories on how the would be examining my ability to quickly process information and drive towards a conclusion with the belief that my grounding in engineering would help me with most of the analytical exercises. What i wasn't expecting was the friendly way in which the interviewers guided me through the case studies, and how positive their body language was even when I stalled for time or took what I felt was too long to answer a question. Great experience overall.
