Back when I was at Harvard Business School, I interviewed for summer internships with the Big Three Consulting firms: McKinsey, Bain & BCG. I got offers from all three. I subsequently decided to work at McKinsey in NYC for the summer (probably stupid – I had an offer from Bain San Francisco).
I did not read any Case Study case books, but I developed my own methodology based on my background as a financial analyst at Morgan Stanley combined with a few things I learned in operations and marketing courses first year. I found that this framework enabled me to thoughtfully address any of the case study questions that I encountered.
I have found that there are three general types of Case Study Questions:
1) Profitablity Questions
2) Efficiency Questions
3) Market Questions
