I Found the LeetCode for System Design Interview, and It's Awesome

Hello Devs, if you're preparing for software engineering interviews, particularly in MAANG, you already know that Data Structures & Algorithms (DSA) and System Design are two key areas where you will be rigorously tested.

While LeetCode is the go-to platform for DSA, system design has always been a challenge.

While there are many websites and platforms to prepare for System Design Interviews like , , and , and I must say, it feels like the LeetCode for System Design.

If you've struggled with structuring your system design answers, getting real feedback, or knowing whether your approach is correct, Codemia.io is a game-changer.

They not only have the biggest collection of System Design and OOP Design problems for practice, but they also have a free System Design course called 

Now, let's check out how Codemia.io can help you to prepare better for your System design and OOP Design interview, and why I think it's like Leetcode for System design.

Most system design resources today are long, text-heavy articles or expensive courses. The problem?

1. No hands-on practice - Reading about system design isn't enough; you need to actively design solutions.


2. No structured progression --- Unlike DSA, where problems are categorized by difficulty, system design prep often feels random and overwhelming.


3. No evaluation or expert feedback --- You don't just need an answer; you need to know why one design is better than another.

This is where 

Instead of just giving you theory-heavy content, Codemia.io provides an interactive, structured, and guided approach to system design. Here's what I loved:

1. Real-World System Design Problems

Codemia.io has over 150+ system design problems, each with a structured approach similar to how LeetCode presents DSA problems.

For example, consider the classic ", and it's also available for free

 is a medium-scale problem, which you can see to get some experience. It's also free.

 --- the AI agent that will help you with the question and solution.

1. If you get stuck, AI provides hints --- just like LeetCode's hint system.

2. If you submit a design proposal, AI evaluates it against industry best practices.

3. You get automated feedback on scalability, fault tolerance, and efficiency.

This bridges the gap between self-learning and expert mentorship.

 goes beyond just system design. It also covers Object-Oriented Design (OOD) Questions. If you don't know, Object-Oriented Design is a common low-level design (LLD) round at FAANG.

Here are OOP problems you can solve on codemia.io to get some practice:

• Classic problems like 
  
  
  

   is also one of my favorites, and Educative.io, whose  has the highest number of practice problems, 120+ and growing. No other platform has that many questions, which is also a big plus point of this platform, and that's why I called it "Leetcode of System Design".

  
  
  

  The second important point is an expert-written solution, also known as an editorial solution on this website. There are more than 80+ such solutions, which are a great resource to compare your solution, learn from them, and also find how to answer such questions.

  
  
  

  What point to mention, what should you discuss, tradeoffs, and so much more.

  
  
  

  Another plus point of codemia.io is that it has object-oriented programming questions, which are not available in other courses, though DesignGurus.io has  is a great platform to prepare for System design and OOP design interviews. You may find courses, but it's hard to find a platform like this.

  
  
  

  I highly recommend it for anyone preparing for System Design and Tech interviews. And, if you want to join now, you can also use the discount code PROMOTION20 to get 20% off now.
