The "20 days" thing was a little bit of a gimmick - I don't recommend reading this if your interview is just 20 days away. You'll probably need a little more time to absorb everything.
But other than that, I thought that this book was a pretty good introduction to handling case interviews. The approach shared was relatively simple, and the frameworks the authors write about are general and high-level (internal vs. external; profit = revenues - costs etc.), meaning that they can be applied to a multitude of cases without too much rote memorisation.
The downside of course is that if the interviewer is looking for a specific framework then you're probably not going to do too well.
Still, having read this book, and perhaps more importantly gone through many of the mock cases, I find that my thinking about business problems has evolved. I find myself utilising the steps espoused in the book in my day-to-day work.
Here they are, and my comments on how I've adapted them to my non-interviewing life:
1. Unwind the case prompt - clarify and paraphrase the problem in your own words. When a colleague comes to you with a problem, ensure you understand it on your own terms, and don't go trying to solve a problem that didn't need to be solved. 2. Develop a framework - some people come to you with problems that are ridiculously open-ended. These "big picture" people (typically senior manager types) have a sense of what they're looking for, but may not be too clear. A framework helps keep everyone sane, even if high-level. It gets the conversation going, and when you're a little into the doing of the work, you and your stakeholders will learn more about the problem, and that nature of the solution that is being sought, and iterate to something closer to perfection. 3. Collect data - enough said. But then again, I was once in a meeting where a stakeholder thought I had all the data I needed, and when I tried to explain that I didn't, things didn't go down very well. It was as if that stakeholder wanted me to make up the data on the fly. 4. Form a hypothesis - important, very important. You want to define the hypothesis, because otherwise you won't know if you're answering the right question. Also, without defining it early on, you'll find a question to fit the data and not the other way around. 5. Test your hypothesis - with the data you've collected, you can now test if your hypothesis stands or not. 6. Summarise the case - because as in every project, there should be an outcome that can be communicated to senior stakeholders and sponsors. 7. Make a final recommendation - because this is essentially what the project was all about in the first place.
