The best preparation for the McKinsey PST: now updated

The best book for your McKinsey Problem Solving Test preparation has been online for only three months, and it’s already being updated. Why? Well, let me share a secret with you about how the ‘Key to the PST’ came to be…

A request from a friend

When I finished writing my other book (“Cracking the Case“) I had asked some friends and colleagues to proof-read the book and distribute it freely if they wanted to help other friends with their case preparation. I received great feedback on my book and made some important improvements as a result.

One of my friends came back to me with a different kind of question: he was preparing for the McKinsey PST and found the section in “Cracking the Case” really helpful. He asked me whether I could write a whole practice problem solving test, so he could practice for the real PST. Since I just completed “Cracking the Case”, I did not really feel like writing another book so soon, but he kept asking and finally I gave in.

The Key to the PST

I drafted some extra questions and let him practice with it. I walked him through the answers and he later aced the ‘real’ PST. He then kept pushing me to share this book with the rest of the world, so I decided to polish the draft a little and put it online on CaseInterviewHQ. It was an instant success and I felt a little scared: it proved to be a great practice together with me walking you through the answers, but what if I wasn’t there in person?

The response I get from my readers however is great: it really helps people finish the PST with more confidence, more time left to review answers and better results. There were still some rough edges and I got great feedback from many readers: thank you! This resulted in the new version of the Key to the PST being released so soon: version 1.1 is available for download right now. It features more clear answer guidelines and some improved formulation of the questions, resembling the real PST even closer.

Thanks a lot for your great feedback (keep it coming) and good luck with your problem solving test and case interviews!

Best,

Stephan.
