I am happy to announce that I've published a brand new edition of Decode and Conquer, the product management interview prep book featuring the world-famous CIRCLES Methodโข.
What can you expect in the 4th edition?
I've made 1000s of changes to reflect the latest trends in PM interviews and preparation techniques including:
Tradeoff Questions
I've introduced two new methods for answering tradeoff questions like:
Should a social media siteโs videos default to autoplay or click-to-play?
How do you decide between a display ad or a โpeople you might knowโ widget in the newsfeed?
Should ConnectTogether require its users to upload profile pictures when they sign up?
The first method is an all-purpose qualitative framework called GCER. GCER stands for Goal, Criteria, Evaluation, and Recommendation.
The other method is for more advanced scenarios, where interviewers expect you to calculate a hard P&L contribution between two options, which I call "before and after" analysis.
Metrics Questions
Those of you who have the 3rd edition noticed that I revamped the Metrics chapter, especially for those preparing for Facebook's dreaded execution interview. I've added new approaches to Metrics questions including:
The TROPIC framework to answer diagnosis questions like "Daily active users for the Facebook newsfeed dropped by 7 percent. How would you diagnose it?"
Guidelines for choosing North Star Metrics for B2C, enterprise software, eCommerce, mobile, and other business types
Strategy Questions
I've streamlined the section on strategy. I now recommend a simpler strategy framework while going into much more detail about key strategy playbooks including:
Differentiations strategies
Niche strategies
Market leadership strategies
Strategies for emerging markets
Strategies for developing markets
Strategies for mature markets
Strategies for shrinking markets
Option value strategies
Strategies to maintain a competitive edge
I have also created a subchapter that simply explains key strategic concepts, from Stratechery's aggregation theory to zero-sum games.
And more
I've rewritten many of the sample answers in the book, added new diagrams, and streamlined numerous explanations.
