DesignGurus.io Review 2025 — Is it Really Worth it? (55% Discount Code)

An in-depth review of DesignGurus.io’s strengths, weaknesses, and must-take courses for cracking system design and coding interviews in 2025 — with an exclusive 50% discount.

Hello guys, as a senior software engineer who has gone through countless system design interviews at top tech companies, I can confidently say that the resources you choose to prepare with make a massive difference.

While I have used multiple resources to prepare for System Design and DSA like ByteByteGo, AlgoMonster, Codmia.io, Educative.io, and Exponent, one of the platforms that truly stood out for me during my preparation journey is DesignGurus.io — and now, in 2025, they’re offering a massive 55% discount, making it the perfect time to check them out.

Tech Interview Preparation – System Design, Coding & Behavioral Courses | Design Gurus

Preparing for technical interviews at top tech companies is no small feat — especially when it comes to system design and advanced algorithmic problem solving.

If you’ve spent hours on LeetCode and still feel unprepared for the “How would you design Twitter?” kind of questions, you’re not alone. That’s where DesignGurus.io comes in.

Created by ex FAANG Engineers like Arslan Ahmad, it’s a platform that’s gained popularity for its practical, pattern-based approach to interview prep — especially in the areas of System Design, Object-Oriented Design, and Grokking-style problem solving.

As a senior software engineer who has personally used DesignGurus to sharpen my own interview skills, I’ve seen firsthand how effective and structured their courses are.

I first come across them while searching for a good System Design course 5 years back during the height of COVID pandemic, at that time, I come across their Grokking the System Design course, which was available on Educative.io, another similar platform.

This was the only course at that time which can teach you How to design distributed System at scale and how to answer System Design questions on both FAANG and non FAANG companies.

At point of time, this course was so popular that it was bringing close to half of Educative’s revenue. Since then, they have moved to their own platform called DesignGurus.io and now you can get all of their System Design and Coding interview courses for just one subscription and the best part is they are now offering 50% discount.

If you are in rush, I suggest go and join the DesignGurus.io for 50% OFF, its totally worth it for its superior and in-depth content you need to impress your interviewer and if you got time, stay here and let me walk through what I liked about this platform and how it can help you prepare well for your next technical interview.

In this review, I’ll walk you through the pros and cons of using DesignGurus, highlight their best courses, and help you decide whether it’s the right platform for your 2025 interview goals.

Let’s dive into what makes DesignGurus.io a great platform, where it shines, where it could improve, and whether it’s worth your money and time.

What I Love About DesignGurus.io?

Here are the main things I really like about this platform apart from the fact that its created by ex FAANG engineers and it covers System Design in depth.

1. Structured and Practical System Design Content

Their Grokking the System Design Interview course has become somewhat of an industry standard. It breaks down complex system design topics into digestible patterns — like cache, load balancer, sharding, rate limiter, etc.

These reusable building blocks are incredibly helpful when solving any real-world design problem or tackling tough interview questions like “Design URL Shortner” or “Design Netflix”.

They also provide nice System Design templates like below which you can use to structure your thoughts and answer. A detailed diagram like this with similar detailed explanation can really impress interviewer.

2. Pattern-Based Learning

They are not just a System Design shop but they provide a complete package to prepare both DSA and System Design.

Since both the System Design and Coding Interview tracks are designed around patterns, not just individual problems, it make sense to learn patterns rather than chasing questions.

This helps you develop a mental model for solving any problem thrown at you — an underrated advantage in high-pressure interviews.

Apart from Grokking the System Design Interview, I highly recommend their Grokking the Coding Interview: Patterns for Coding Questions and Grokking Dynamic Programming Patterns for Coding Interviews courses to master coding interview patterns and Dynamic programming techniques.

They even have company specific courses like Grokking Meta Coding Interview and Grokking Amazon Coding Interview where you can prepare especially for Big Tech or FAANG companies with lots of previous questions and insights.

3. Excellent Visuals & Diagrams

When it comes to visual learning, I think ByteByteGo rules the world but if you ask me who is next then I would say DesignGurus.io because they are another platform which provides detailed visuals and cheat sheet like the one shown below

One of the strongest features of their courses and study material is the clean, intuitive diagrams that accompany almost every lesson.

As engineers, we often process visuals better than text-heavy explanations, and DesignGurus really nails this aspect.

4. Real Interview Focus

They focus not just on learning, but interview readiness — how to communicate your design, what trade-offs to discuss, and how to make your solution scalable and fault-tolerant.

They also provide templates and cheat sheet like the one shown below to help you remember the key concepts.

What Could Be Better?

Let me be honest and blunt here, DesignGurus.io is not perfect. Since I have been using many platform, I know what is missing and how can make the DesignGurus.io even better.

1. Limited Interactivity

While the written content is fantastic, I found myself wishing for more video walkthroughs or interactive quizzes. If you prefer video-based learning and online practice like on Udemy or Educative.io, you might miss that dynamic here.

2. Coding Course Depth

The Grokking the Coding Interview course is good, but not as extensive as LeetCode or other platforms. It’s ideal for grasping patterns (like sliding window, BFS, fast & slow pointers), but you may still need to supplement it with hands-on practice elsewhere.

Though, with the 55% discount they are offering, it becomes no brainer to join DesignGurus.io now and level up your System Design and DSA concepts before interviews.

If you want, you can use the remaining money to join AlgoMonster, Codmia.io, and Exponent,for hands-on coding and mock interviews.

5 Best System Design and Coding Interview Courses on DesignGurus.io for 2025

If you’re considering the platform, here are the top courses I personally recommend:

1. Grokking the System Design Interview

The flagship course. Covers modern system architecture principles with step-by-step breakdowns of questions asked at FAANG interviews.

3. Grokking the Coding Interview: Patterns for Coding Questions

This is another awesome course on DesignGurus.io for understanding problem-solving and templates you can reuse. It’s a more structured alternative to brute-force LeetCode grinding.

This one also the first online course I found which introduced coding patterns, before this I used to mug up as many coding problems as possible.

4. Grokking the Object-Oriented Design Interview

Very useful for low-level design interviews, especially if you’re applying for backend or full-stack roles. You will solve many popular OOP Design problems like vending machine design, parking lot design, and message broker design like Kafka.

My Experience Using It

When I was prepping for system design rounds at companies like Amazon and Stripe, DesignGurus gave me a huge edge.

The clarity with which they explain distributed systems, databases, scalability strategies, and trade-offs helped me not just answer questions well, but actually impress the interviewers.

If you’re a mid-to-senior developer aiming for top-tier companies, this platform is tailored for you.

The first course I joined on this platform was Grokking the System Design Interview and then I bought Grokking the Coding Interview: Patterns for Coding Questions and all of their grokking courses until they launch a subscription.

Now you can get access to all of their courses with just single subscription, but if you need lifetime access then you can also get their All course bundle, where you can get all of their Grokking courses for a big discount.
