Outdated and incomplete, but definitely still worth reading

This is one of two classics when it comes to PM interview prep, along with Cracking the PM Interview. I remember reading this book years ago and decided to pick up the latest edition last week, as I am preparing to make my next career jump after 5 years as a Product Manager at Apple. Sadly, the book is nearly identical to the previous black-covered version; even the typos and outdated examples remain unchanged.
I think the biggest drawback of this book is for anything involving business strategy or open-ended product questions, as there's next to no up-to-date examples included. For this reason, I would recommend reading this book in conjunction with another book called Swipe to Unlock. While Swipe to Unlock isn't a PM interview book, it was written by PMs at FAANG companies and it provides a hyper-recent overview of the latest tech trends, strategies and key insights for everything important that happened in tech up till around late 2019. It also breaks down a lot of more recent strategy questions involving all the top companies (eg. Why did Microsoft Acquire LinkedIn, Why does Uber continue to use Google Maps instead of building their own maps even as Google's self-driving cards continue to make advancements, etc.).
In my opinion, if you own the previous edition of this book, it's definitely not worth buying the new edition. However, if you haven't read this book, I think you should. Although some of the examples are outdated, the overview of the different types of questions you might get asked along with the example questions and answers are still helpful to review. Between reading Decode to Conquer and Swipe to Unlock, I have found myself extremely well-prepared for all the PM interviews I have had thus far (Google, Slack, Facebook and Pinterest).
