Review — Is ByteByteGo a Good Place for Coding Interview Preparation?
Yes, ByteByteGo is definitely worth it and now with improved content its one of the best resource for System Design and Coding Interviews.
Hello guys, If you are preparing for coding interviews in 2025 — whether it is for FAANG companies, startups, or top product-based firms — you might have already heard about ByteByteGo.
Founded by Alex Xu, the author of the well-known System Design Interview — An Insider’s Guide, ByteByteGo has built a solid reputation in the space of system design learning.
But what about coding interview preparation?
Is ByteByteGo really a good platform if your goal is to crack the coding interviews at companies like Google, Amazon, Microsoft, or startups?
Earlier, I have shared my review of ByteByteGo on System Design interview preparation and In this article, I will share my honest review, based on my own experience of using ByteByteGo as part of my interview prep journey.
Let’s break it down properly.
What is ByteByteGo? What Does it Cover?
In simple terms, ByteByteGo is a text-based learning platform that focuses on helping engineers understand complex technical topics like system design, machine learning system design, Generative AI system design, object-oriented design, and now increasingly, coding interview patterns.
The platform is created and maintained by Alex Xu and his team — many of whom are ex-FAANG engineers — and is known for its crisp diagrams, detailed step-by-step explanations, and case studies of designing popular systems like YouTube, WhatsApp, Google Maps, etc.
I first come across ByteByteGo a couple of years go by following their detailed visual diagram on System Design topics. Since then the platform has evolved into a complete package for coding interview preparation.
Initially ByteByteGo was the digital version of System Design Interview — An Insider’s Guide Volume 1 and System Design Interview — An Insider’s Guide Volume 2, but now its a collection of more than 7 books and covering key coding interview topics like Object Oriented Design, Coding Interview Patterns, Machine Learning System Design, and Generative AI System Design.
Precisely speaking it contains following books content:
- Coding Interview Patterns: Nail Your Next Coding Interview
- Machine Learning System Design Interview
- Generative AI System Design Interview
- Object Oriented Design Interview: An Insider’s Guide
and a couple of books are already in pipeline on Mobile System Design and Behavioral Interview.
Now with the relaunch of the ByteByteGo website and this amount of content ByteByteGo become even more useful for anyone preparing for Coding Interviews.
Not just System Design but you can also work on your coding problems skills by learning Coding interview patterns.
If you ask me the value ByteByteGo is offering now is really immense as all of these books are quality books and if you consider their visual guides then it becomes on of its kind resource to prepare for coding interviews.
Another great thing is that they are now offering 50% discount on their annual and lifetime plan, which means you can get it for just half price. I have got the lifetime plan because it offers more value and I know I will need it through my career, you can do the same.

Does ByteByteGo cover Coding Interview Preparation?
As I told you before, traditionally, ByteByteGo was focused mainly on System Design. However, over the last year or so, the platform has expanded and now includes:
- Coding Interview Patterns — A dedicated section that discusses frequently asked coding patterns like sliding window, two pointers, binary search variations, recursion + memoization, and more.
- Mock Interviews & Quizzes — They have started adding interactive elements where you can test your knowledge of coding patterns and design trade-offs.
- Real-world code examples — Some sections also explain how certain data structures or algorithms are used inside large-scale systems (e.g., how caching works in real systems).
However, let me be very clear — ByteByteGo is not a pure DSA practice platform like LeetCode, HackerRank, or Codeforces. It does not have a large database of problems for you to solve hands-on with code editor integrations.
The focus is more on understanding patterns, trade-offs, and solutions rather than endless coding practice, similar to AlgoMonster which focuses on coding patterns.
They have a couple of free chapter on Coding interview patterns which I highly recommend you to checkout before you join. Their chapter on Two Pointer Pattern is one of the best explanation I have read. In fact, you can see it yourself
They also provide coding examples in Python, JavaScript, and Java, three major programming language. This feature is not available in books but on ByteByteGo platform where you can choose the programming language on any code example.
What I Liked About ByteByteGo for Coding Interview Preparation?
In order to crack the coding interview, you need to master two main topics, first Data Structures and Algorithms and second System Design. ByteByteGo used to cover the System Design but now with addition of coding interview patterns, it now also covers DSA.
Here are the few things I liked about the platform:
1️⃣ Great Focus on Patterns over Random Problems
What I found most useful was that ByteByteGo does not bombard you with 500+ problems. Instead, it focuses on common patterns that underlie most interview problems. This helps in developing a problem-solving mindset rather than brute-force grinding.
2️⃣ Clear, well-explained diagrams
Many times when I get stuck on a problem, it is not about code — it’s about understanding the approach. The diagrams on ByteByteGo really help in visualizing how algorithms work (e.g., how two pointers move, how sliding window expands/contracts).
3️⃣ Real-world system linkages
ByteByteGo does a good job of explaining where certain coding patterns or algorithms appear in real systems. This makes preparation more meaningful, as you don’t just solve abstract problems but understand their application.
4️⃣ Regular updates
Unlike books that are static, ByteByteGo platform keeps adding new patterns, explanations, and even mock interviews. The coding patterns section has grown quite well in the last few months, especially after including the content from Coding Interview Patterns: Nail Your Next Coding Interview book.
Now, you can get all the content on the platform itself.
Where ByteByteGo Can Improve for Coding Interviews?
While ByteByteGo has made great improved, especially after re-design and with so much advanced new content on OOP Design and Machine Learning and Gen AI System Design, they can still do few things to make the website even more valuable, like:
1️⃣ No built-in coding environment
If you want to actually code and submit solutions like you do on LeetCode, ByteByteGo does not provide that. You will have to write code separately on your local machine or another platform.
2️⃣ Limited problem sets
If your goal is pure coding practice — solving 100–200 problems before the interview — you’ll find ByteByteGo lacking in that department. It’s more about quality explanations than quantity of problems.
3️⃣ Mostly text-based
If you are someone who prefers video lectures for coding interview prep (like on Udemy or YouTube), ByteByteGo may feel a bit dry. It’s heavily text + diagram focused.
Although, their visual library mitigate this disadvantage by offering self-explanatory, high-quality diagrams like shown below:
How I Use ByteByteGo for My Coding Interview Prep?
I love to give interviews and I do this every year to see where do I stand in the modern era of senior software engineer interviews.
Personally, I have been using ByteByteGo as a supplementary resource rather than my primary coding practice platform.
Here’s how I combine it:
✅ I use ByteByteGo to study and master patterns, and understand design trade-offs (e.g., when to use sliding window vs. prefix sums).
✅ I then go to LeetCode, HackerRank, or Codeforces to apply those patterns on actual coding problems.
✅ For system design prep, I rely on ByteByteGo extensively because that is where it truly shines.
This combination gives me both the conceptual clarity (from ByteByteGo) and coding speed + accuracy (from problem practice sites).
But with now improved design and full content on Coding interview patterns, I will be using ByteByteGo more to brush up my problem solving skills for sure.
And, with 50% discount they are offering now, its really a no brainer to join this site. I have recommended it to both my friends and my readers who are working as software engineers, tech lead, and senor engineers.

Is ByteByteGo worth it for Coding Interview Prep?
If you ask me ByteByteGo is 100% worth it for coding interview preparation especially if you want conceptual clarity, pattern mastery, and links to real-world systems.
The new re-design of website and improved content library, especially the content on Coding Interview Patterns, OOP Design, and Machine Learning and Gen AI System Design really makes the website worthy for any coding interview preparation in 2025 and beyond.
Though, this platform may not be worth for you if you are looking for hundreds of problems to grind through or an online judge to test your code, for that I recommend LeetCode or HackerRank but still you can combine ByteByteGo with them for better result.
As ByteByteGo is best thought of as a bridge between theory and practice. It helps you build the mindset and framework to approach coding problems, but you’ll still need to code those solutions yourself elsewhere.
Who Should Consider ByteByteGo for Coding Interviews?
✅ Engineers who want to understand coding patterns deeply rather than just memorize solutions
✅ People preparing for system design + coding interviews together
✅ Mid-level/senior engineers who want to brush up on patterns and their real-world relevance
— -
Who May Not Find it Sufficient Alone?
❌ Freshers or early-stage candidates who need lots of hands-on coding practice
❌ People looking for gamified coding platforms or coding competitions
Now, when it comes to success stories, a lot of people have used ByteByteGo to get job in FAANG and other top companies like NVIDIA, PayPal, ROBLOX, TikTok, Netflix etc.
Consider the study material and the value it provides, particularly the visual learning material, I think ByteByteGo is 100% worth it for coding interview preparation and an indispensable resource for Software Engineers.
Combine that too with the 50% discount they are offering now and it become even more worth it. If you always wanted to join ByteByteGo then now is the best time.
Here is the link to get your discount — 50% OFF on ByteByteGo.
Conclusion
Overall, ByteByteGo is a great addition to your coding interview toolkit, but it should not be your only tool. If you are serious about coding interviews, I recommend combining it with a coding practice platform like LeetCode, and possibly also doing mock interviews (BugFree.ai, Exponent, etc.).
If you enjoy learning through diagrams, real-world applications, and step-by-step breakdowns of coding patterns — ByteByteGo is definitely worth checking out.
