To all those who are preparing for upcoming interviews...
The Harbus, the student newspaper of HBS, publishes a list of approximately 100 real MBA interview questions, accompanied by detailed analysis of how to answer them. It's the only guide out there that is written by actual current MBA students, so it is straight from people who have actually successfully made it through the interview process. The list is constantly updated and contains actual interview questions from the latest application round. It is written by HBS students, but is very applicable to all business schools.
