You've helped many people in more ways than you know. I wish to do that someday in my own way.
Just wanted to share my gratitude for your work!
Bought Decode & Conquer and enjoying every page. :)
I am a Zimbabwean who has been living in China for the last 8 years. No direct PM experience but your 2-week PM guide
has been incredibly useful . I have also been reading
Decode and Conquer which has gotten me up to speed really fast.
Brilliant book!
I have just about finished your book Decode and Conquer and have found it to be enlightening.
I feel that I already have drastically reduced the amount of PM interviews that I would have failed with a deer in the headlights look on my face.
Lewis Lin is the best.
Just heard back from Uber, it’s a yes! I had interviewed there twice before over the years, but it wasn’t until I encountered Lewis, his materials, and this community that I was finally able to crack it .

Your books helped me when I first got the PM job at Amazon . They again helped me refresh, alongside my gained experience, when I moved to Google. That, as you know, is through an interview process that’s notoriously one of the hardest in the industry.
The shared wisdom in the pages of the book (even when I sometimes disagreed with the methods and answers)
was extremely helpful . Verified Purchase
I was pretty anxious preparing for my PM interview with Amazon, so months prior, I asked around to see what books to read, and Decode and Conquer was one of the most highly recommended books.

It lived up to my expectations and beyond. Loved it. There’s no fluff; it was to the point, fruitful, and easy to follow. I loved how examples were often explained using a dialogue between an interviewer and a candidate. Helps you envision what the real interview will be like and prepares you well.

Everything about this book is memorable and lovable. Not long after reading it, I went into my interviews at Amazon and landed my first PM role.

This book is a must-read for anyone preparing for their upcoming PM interviews. If you’re considering getting this book at all, I highly advise that you get it. Decode and Conquer, 4th Edition
