I Tried Both Udemy and Educative? Here is My Honest Review

Hello guys, if you are wondering the difference between Udemy and Educative and whether you should take Udemy courses or join the Educative platform to learn new tech skills, you have come to the right place. Earlier, I have shared a comparison between Pluralsight and Udemy as well as CodeCademy vs Pluralsight in this article, I will compare Udemy with Educative, a new text-based, interactive learning platform. While I have often said that Udemy is my favorite platform because you can get high-quality and comprehensive courses from top instructors for just $9.9, which is phenomenal.

In this article, we will explore why system design interviews matter, the challenges they pose, and how Codemia.io can become your ultimate partner to crack these interviews in 2026.

Why System Design Interviews Matter?

System design interviews evaluate your ability to solve real-world engineering problems. These interviews test various dimensions of your technical expertise, including:

  1. Scalability: Can your system handle millions or even billions of users?
  2. Performance: Is your solution efficient in terms of latency and throughput?
  3. Reliability: Can your design ensure minimal downtime?
  4. Maintainability: Will your system remain easy to update and debug over time?
  5. Communication: Can you articulate your design ideas effectively to your interviewer?

Companies, both large and small, value these skills because they reflect how you’ll approach designing the architecture for large-scale, complex systems in real-life scenarios.

If you ace your system design interview, it’s a strong indicator that you can thrive in a challenging engineering environment.

Though, its not easy and you need to prepare hard to crack System design round, though, resources like Codemia.io help as they give you real questions and also provide framework to answer any system design question.

Their editorial solution is also a great example on how to structure your answer or solution on interview. For example, you can see this expert solution of Twitter System Design to get some ideas.

Why Cracking System Design Interview is Challenging in 2026?

Despite their importance, system design interviews are notoriously hard to prepare for, even for senior developers who have created multiple applications or supported real world applications in production.

Here’s why:

  1. Broad Scope: System design problems span a wide range of topics, including databases, caching, distributed systems, networking, and more.
  2. Open-Ended Questions: Unlike coding questions with a definitive solution, system design questions are often ambiguous, requiring you to define the scope and make trade-offs.
  3. Lack of Resources: While there are many platforms for coding interview prep, resources for system design are relatively scarce.
  4. Time Pressure: You’re expected to design complex systems within a limited timeframe, often leaving no room for hesitation.
  5. Interviewer Expectations: Understanding what the interviewer is looking for — such as clarity, creativity, and knowledge of system design trade-offs — can be tricky. Though, you can check my following article where I have shared 15 essential software design tradeoffs which every developer should be aware of.
