The book is a true answer to the title as is teaches what they don’t teach you at harvard business school. I agree the title is poking fun at most prestigious business school in the world but in my view business schools these days don’t teach you what they meant to be.busines schools in these days are more of an academic intrest and teach you all the tricks whcih were valid 50 years back. so this book tells how the real life goes how do we do business in real life what is taugh at business schools is all fictional I can say that as I have also done my MBA . the book is full os rue stories about how the author encountered a problem and how did he solve it. this is a practical book which gives you no big thoughts but tell you I reality how you should do it. a must read .if you don’t have time and resources to do an MBA please read this book. this is all I can say and you won’t regret this decision.
