It's a collection of cases you can use to practice but they are not cases used currently by interviewers.

Hey anonymous,

This is a collection of old cases used in actual interviews. Even if they are not used anymore at McKinsey, they are really powerful as i) they give you a good sense-check of what the actual cases look like; ii) they tend to focus on the same industries and problems that the ones currently being used.

@B, Andrea, anyone else,

Has anyone actually seen this book from mckcasebook.com or can confirm this is a fraud? I was considering purchasing it. I wanted to write to site administrator, what does it mean "100% money back guarantee", but the contact form on the website informed me, that it doesn't work and I should try the other way (sic!). Seems most likely like a fraud, but don't understand why B and Adrea would write that this book can be useful.

Thanks in advance
