The Product Manager Interview: 167 Actual Questions and Answers

One thing to note that I didnt quite realize when I bought it is that this is a big book! Not just in length, but in actual size (8.5" × 11")...like a textbook/study guide. On the plus side, this makes it easier to read and gives extra room for the many diagrams.

Great book! Very concise in its content and messaging. It helps to have this as the LAST book you use to tie together all other PM case trainings.

Not sure if real world interviews value this approach...followed this to the tee and still got dinged

I was blown away by this book.For 70% of the book, Lewis teaches you how to fish. By that I mean he walks you through how to understand, digest, and produce the best answers for any PM interview question. For instance, "How would you go about pricing UberX?" or "Design a better Starbucks." I'd heard that his books were packed with examples and sample problems, so the academic workbook approach didn't surprise me.What I didn't expect were the number of sections where he just gave you the fish. 30% of the book was pure textbook. It gave me so many numbers I never would have thought to look up. For instance, in his estimation question section, it didn't say "know the number of internet users in USA, Japan, Brazil, and China before your interview" it just gave you those numbers - for each key region, country, and population. And he does this 10x over - for population sizes, smartphone facts, streaming services, eCommerce facts, online advertising numbers - I just memorized the numbers on the page and didn't waste any time googling.On top of that, he also provides cheat sheets, evaluation sheets, interview plans, study guides - it was a cornucopia of printable resources.Time-wise, this book did take me a bit to get through it. There are so many examples and sample problems, I highly recommend buying this book at least a week or two before your interview, depending on how comfortable you are with PM questions. There's a lot of content, so the more wiggle room and cushion time you can give yourself to absorb the content and practice demonstrating your thought processes the better.Overall, I'd highly recommend this book. His step-by-step breakdowns are some of the best that I've seen. Thank you!

Super happy with the purchase of this book! I was definitely feeling the pressure for the PM interview I had coming up and was scared to walk into the interview only to be blind-sided with numerous questions. This book helped me to feel prepared and was a complete game-changer. I would recommend even on a tight schedule, as there are so many quick sample problems to choose from.I really appreciated how the book was filled with various incredibly helpful facts. Whether it be the value of companies, ad revenue or even the number of users on Pinterest, the numbers are there! Instead of hypothetical businesses like the examples I have found in other books, Lewis’ problems are shaped around real-world examples (ie. Dropbox and Google Maps).Had previously read Decode and Conquer (also by Lewis) and was surprised at how much the information from that book aligned with the problems and examples found in this one. Would definitely suggest buying them together. Already lending both out to many of my recent grad friends looking to enter the competitive tech fields.Thank you Lewis!!

First off, would highly recommend signing up for Lewis’ slack group which he mentions near the beginning of the book. After signing up for this it has been a game changer, now that I have people who are willing to help me practice PM interviews.I have a difficult time with numbers and always get extremely stressed out when it comes to technical problems related to math, but the chapters on Pricing Analytics and also Metrics were insanely helpful. In each example, the sample conversations were very well thought out and both concise yet helped so much with my understanding of the concepts.I never could have even thought of so many of the examples provided in this book, and I am beyond glad I bought it before going through recruiting. This book is packed from beginning to end with study guides and tips and very detailed examples for all kinds of PM interview problems.

If you are trying to learn or dip your feet into PM interviewing for the first time, I don't think this is the book for you. This is only a book I can recommend if you want a large bank of accurate sample questions with okay answers.There is very little discussion on the frameworks used and you definitely need other books to learn that first. A good chunk of answers felt really surface level in my opinion - they are not answers I would feel happy with giving in an interview. There is also little to no explanation on how answers are crafted or why a sample answer went one route versus another.I would try Decode & Conquer or Cracking the PM Interview first if you're learning or haven't read those yet.

I bought this book and "Cracking the PM Interview" and this one is better. When it comes to product problems, I needed to approach the problems more holistically, from start to finish. This book directed me better, and helped me reach solutions faster. This book had a more complete finish - it built my PM muscle. Cracking the PM interview is more like a collection of random points with no glue.

Lewis Lin has been an inspiration for me for quite some years now.I always wanted to have this book but finally I can say I am a proud owner of it. Overall the book is a good refresher for the product management interview preps.

Opening Chapter it advises the reader buy the Authors previous books. Pretty good advise because it makes this book useless otherwise.
