It has a four-step framework to solve any system design interview question, giving you a bigger picture to understand the fundamentals of system design. With this annual pass, you can also get the insiders’ take on what the interviewers look for and the reason behind it.

This book also features 26 real-system interview questions and detailed solutions that are easy to understand. More importantly, it contains more than 500 diagrams that explain how different systems work visually so you can see and quickly point out the differences.

This book is an Amazon bestseller that has been translated into six languages and has become very remarkable among people in the field. To access the text and the yearly and monthly materials, you can pay $59.99 annually!

As we’ve mentioned, the website currently only offers two kinds of books. The second one is the ByteByte Machine Learning System Design Interview written by Ali Aminian, a staff machine learning engineer at Adobe and ex-Google.

He has expertise in machine learning and large-scale distributed systems. The Bytebytego system design PDF book contains 11 lessons, which you can enjoy for only $34.99 per year. In addition, it features a 7-step framework to solve any ML system design interview question.

Here, you can learn insider information about what the interviewers search for and the reason behind it. In addition, the 10 real ML system design questions also come with detailed solutions to help you have more profound information.

In the ByteByteGo PDF book, you’ll discover 211 diagrams explaining how multiple systems work in the form of images that make it much easier to understand.  You can check the link below to get a sneak peek of the book!

ByteByteGo offers a text-based course on system design interviews, which is ideal for programmers, software engineers, and developers who want to improve their skills. However, anyone in the field can take this course, whether they’re preparing for a system design interview or not.

In addition, ByteByteGo books and services provide easy-to-understand and comprehensive information, including crucial computer science concepts. So, they’re best for beginners and experienced developers who want to brush up on system design concepts before the interview.

When we talk about both books they offer, there is no doubt that there is a tremendously positive review across the media, but on its website, they don’t have a review section.

Still, we found it has a significant number on social media where users share their experiences. Also, many people on Reddit talk about this course and book. However, on Trustpilot, it has a low rating.

Here is one of the reviews from the user:

I want to thank Alex Xu. Firstly, two days ago, I got this book, read the first chapter, and was lucky enough to be in the system design interview. It really helped me a lot.

Another user also said about the System Design Interview – An insider‘s guide:

I just obtained a copy of @alexxubyte and @sahnlam’s book, and after scanning a bit, it looks excellent, not only to prepare for interviews but to comprehend some new patterns! I am also thinking of doing a giveaway! Details on that soon.

Below is one of the reviews on Amazon from the Machine Learning System Design Interview book:

This book seriously runs into great depth and diagrams how to employ software engineering in today’s world. Moreover, it’s very easy to read and understand!

From the testimonials above, we noticed that most customers were satisfied with the book, which helped them gain new knowledge and prepare for the system design interview.

As far as we know, there are no negative reviews about its subscription since it is very insightful and provides updates on the new lessons.

You may still be skeptical about this service since ByteBytego doesn’t offer a refund policy. However, we think it’s not a big deal since it provides a risk-free experience with the free trial.

Aside from that, a secure website is guaranteed with the use of HTTPS and an SSL certificate. So, we think this company already has proven legitimacy, whether for the service or website access.

In our honest opinion, after gathering all the information for this ByteByteGo review, it is really worth it for everyone who wants to learn machine learning and system design.

Furthermore, online access to the book lets you access the easy-to-understand diagrams with in-depth knowledge. Moreover, the authors use language that makes the technical concepts much easier to understand.

One noteworthy aspect is that it can provide resources that cannot be found easily. For instance, it includes knowledge of how big scalable systems work in Amazon, Spotify, Google, and others.

So, this is the best investment for developers to learn the system design concepts vital for designing a scalable system that can withstand the production time test. Its subscription is also the most comprehensive, updated, and engaging in any form.

Even better, the case studies make learning much more fun. Lastly, considering the diagrams, explanations, content quality, value, and price, it is the best money to spend on learning system design.

Unfortunately, ByteByteGo offers no refunds, and all purchases are final. However, you can enjoy the free content or preview to help you decide before purchasing the course.
