Deloitte Management Consultant interview questions

The interview process consisted of a maximum of three rounds over a single day (each round is an elimination round). Interviewees were assigned 'buddies' over a month in advance to beef up consulting skills. On interview day, 1st round is usually a guesstimate round lasting ~20 min (E.g. How many gallons of water were consumed in Los Angeles yesterday or How many gas stations are there in Chicago?). Once a candidate clears the 1st round, the 2nd round is a more structure case interview with a two member panel. This lasts about 30-40 minutes. On clearing that, there is a final partner round which lasts ~20 min.
