McKinsey & Company Interview Question

What was unexpected was that I basically received the same question for both my Interviews, except differently worded, i.e. name a time you resolved conflict/demonstrated leadership. However, one of the cases was very confusing based on interviewer's wording. It was a question that asked you factor CO2 emissions for fuel vs. electric cars, hence a value chain question, but the interviewer's wording obscured that consideration.
