In total it contains 12 different case interview frameworks to go through and work at your own pace. Notably, it is the best-selling case interview book on Amazon for a long time.

Overall, these three books are not exhaustive of the numerous books available to you. However, it is important to note that this needs to complement the company research you’ve conducted as well as your interest in business affairs.

This approach and roadmap needs to be rooted in rigorous logic. This is completely different from the so-called framework learning philosophy brought forward by most case books. Hence why it is important to apply knowledge from these books but it should not be your foundation to tackling the questions, instead rooted in meticulous and attentive logic.
