If you want to practice case questions, I highly recommend Marc Cosentino’s book Case in Point.
You can also access sample case questions from various consulting clubs here, and from the following consulting firm websites:
- McKinsey & Company;
- Bain & Company;
- Oliver Wyman;
- A.T. Kearney;
- Accenture; and
- L.E.K. Consulting.
