I had applied for over 200 jobs over 6 months and finally got my CV to the level that I could reliably land interviews. I actually have pretty good experience from being a startup founder, but I could never make it past the hiring manager interview. After doing your course, I went from my interviewers clearly not satisfied with my answers to them being just blown away. I started hearing comments like "Wow, you are such a strong candidate. You really want to work for us?" I landed my exact dream job handily and start working there in a couple of months. I think the most crucial part was the insight about the Amazon leadership principles plus the framework for organizing the stories. I sometimes would use 3-4 of my stories in the interview and could see the interviewers getting excited while I was talking. Great feeling. Great validation. Thanks so much.

I purchased Diego's Product Interview OS course four days before my interview, and I learned a lot from the course. It helped me to prepare for the PM interviews in a systematic way for both behavioral and technical questions. The most I benefit from is the frameworks that Diego has shared with us in the course for answering different type of questions of product management for. I have done a lot of PM work but never realized there are frameworks I can follow to answer the questions in the interviews and to apply to my daily PM work. Also the 1:1 sessions with Diego were very helpful too, he coached me and provided great advice. I will definitely recommend him for this course! Thank you Diego! Viv

I recently landed a role with Meta as a Rotational Product Manager and Diego's courses really helped me with the interviews. My PM experience is very limited (1-2 years) and with Diego's course I was able to learn how to properly answer product sense/design, analytical, and behavioral questions. One thing that I appreciated about the course was how in detail Diego goes, he'll list the framework/best approaches and gives an examples and then dissects the answer given. The courses also had a handful of mock interviews as well. I would recommend this course to anyone who is new to PM, who wants to refresh their interviewing skills, and those interested in learning more.

The course has helped me structure my thoughts and I feel more confident answering any product question. Best thing about the course is Diego has covered the framework in depth with very relevant examples. The mock interviews with Industry PMs is also helping me approach the real interviews better. Would highly recommend this course to all PMs or PM aspirants.

I recently completed the The Product Interview OS and I have been extremely satisfied with the results. Diego structured this course in a very systematic and pragmatic approach. It is very clear and understandable. One of the best things about this course is the focus on preparing for product management interviews. The course provides a comprehensive overview of the types of questions that are commonly asked in product management interviews and provides practical tips on how to approach and answer these questions. It is more about the approach and understanding rather than a memorization. Overall, I highly recommend The Product Interview OS for anyone looking to break into the product management field. The course is well-structured, engaging, and provides valuable insights that can be immediately applied in the job search process.

I am transitioning to Product and I find this course VERY helpful in preparing for interviews! Diego lays out wonderful frameworks and examples for interview prep. The material is organized, easily understandable, and designed for you to succeed! If you have any questions, you have access to the Slack community where you are supported by not just Diego himself, but also everyone on the same journey. This course is well worth it. Diego is one of the best, most genuine mentors out there and has a record for supporting people in their journey to Product!

The Product Interview OS is one of the most detailed courses I have seen for cracking PM interviews. It's starts with answering the basic introduction questions and goes in detail on how to crack complicated design and strategy questions. This program is definitely worth your investment.

Product Interview Operating System is fanatic course! I have gained confidence in my job interviews and the resources are very thoughtful.

As someone who was trying to break into Product Management from a business administration background, thus course helped me understand what recruiters are looking out for during interviews and how to give them what they want. The frameworks and concepts are well explained for easy understanding. I aced majority of my interviews and landed a role after 4 months of trying to transition in Product Management. Thank you Diego!

Diego breaks down the approach to answering product design and execution questions extremely well. Even if you don't know what the product is, or how it works, the base framework shared by Diego enables you to tackle virtually any question presented to you. The mock interviews were not super helpful, but Diego's examples where he "interviews" himself were of much higher quality. This course has excellent content and an unbeatable price. You get much more bang for your buck when compared to others out there, such as Product Exponent.

I’ve been doing the course for a while now. It’s making the concepts pretty clear. I’m an entry level product manager applying for senior roles. This course has been quite helpful for me.
Dec 19, 2022
I had gone through many materials for preparing PM interviews but was never confident enough until I went through Diego's course. While every one knows types of PM questions and what to answer but this course has mastered the way how to present the answers to really create a differentiation. I see the impact through my several mock interview feedbacks and the credit goes to this interview course. I would definitely recommend Aspiring or current PMs to take the value of this course

I purchased the course couple of days ago as I am preparing to move to PM roles. Having gone through parts of the course, it's proving to be immensely valuable. I particularly liked the estimation framework and how clearly and quickly Diego explained concepts. Moreover, FAANG sample interviews are a great addition.

The course was actually a really good surprise! I was overwhelmed about applying to new jobs after being too long working for the same company, not knowing what to expect and how to answer common questions and this course gave me a simple and structured method to answer those questions. I feel much more confident now.

The masterpiece crafted by Mr Diego has helped me not only to prepare for interviews but also in my day to day PM practice. The course is by far the most structured course to crack any PM interview. The frameworks given in the course helps me not to sound robot during interviews. Other than course which I really loved the most is the community, you'll get a chance to join the slack channel wherein all the members would help you in many forms. Even Diego will personally reply most of the times. Icing in the cake is that you can ask for mock interview from the community. Definitely 5/5 for the course. You don't need any other courses if you have this.

After looking at many options, I picked Diego’s course as it focused on teaching you the framework instead of just the mock interviews with established PMs. This course is helping me frame my answers in a systematic way.

Diego’s Class is amazing. So much great content that really helped me with my interview prep. The frameworks are simple to remember and really assist in tying real world application and interviewing together.
Dec 18, 2022
The course is a one stop destination for nailing product manager interviews - seeing all these books, blog posts, videos etc online made me a little anxious if I will be able to cover all the concepts and frameworks etc. but Diego's course has all the essentials in small digestible nugget videos. Plus the slack community is always there to help which is an added bonus. I am using the STARL and STEP frameworks extensively to prepare for my interviews.

This course is much more straight forward and to the point compared to another course I also have access to. I use this course before all of my product interviews and it's really helped me think through how to best answer questions!

I have taken multiple PM courses to learn more about the roles and responsisbilites but I was struggling to express myself and my train of thoughts in clear and concise manner which led to rejections. This course helped me form a framework to answer in best possible way in the limited time I had during interviews. Best part of this course lies in practical explanation using examples which helps to vizualize the framework. Great course! Highly recommened to anyone who has their PM interview soon! Good luck.

Even though I'm not new to Product Management, I thought that there were few areas which I considered as my relatively weaker points and wanted to improve on that. After going through reviews of thus course, I decided to try this and bought this course. I vouch that this has really helped me address my weak areas as the concepts and how to put it to use has been explained very well. I feel its value for money and will definitely recommend this course to people who are looking to ace the PM interviews
Dec 19, 2022
The course has been very helpful in providing me with insight from an insiders perspective on the best way to win at PM interviews !!. The best thing for me have been the practical examples that are littered across the different lessons . I am extremely happy to have come across this resource !.

I am super excited to write a review for this Product Interview OS Course by Diego. First things first: Diego is an absolute "ROCKSTAR". He simplifies PM concepts into small, consumable, easy to understand chunks of knowledge, there is no boring, 1 hour long content! I like how he has drilled down the concepts and transmits it into an easy to understand way. For a beginner/aspiring PM, this course is heaven-sent because instead of having to spend 2-3 weeks reading various books on PM, Diego gives the know-how in a convenient and easy manner! He just does not take a "Because I told you so, you do it" approach, instead Diego, takes the time to explain the "why" behind everything with personal examples, which is super cool and I deeply appreciate it! Highly recommend this course to anyone who wants to break into the PM field.
Dec 19, 2022
Sam here. So I have paid some pretty penny for to be a product manager over all. And some of those course were not comprehensive as Diego course right here. If you want to be a PRODUCT MANAGER, going through the interview phase and sure of it. This training is worth your time and effort.

The thing I like this course the most is the examples Diego offered after he explained the concept or frameworks, which really helps me to come up with my own unique answers that I can respond to if being asked in an actual interview.

I am thankful to this course for helping me become more prepared for the interviews and helping me feel more confident in my strategic thinking as a product manager. This essentially gave me confidence to negotiate compensation and go for a company who offered me best growth as opposed to the next available opportunity! It is extremely comprehensive and at the same time very digestible. Best thing about this course is the slack community and Diego for being extremely responsive and thoughtful of everybody's time.
