Introduction
Even in an era where artificial intelligence can generate substantial amounts of code, the skill of systems design remains irreplaceable. Crafting scalable, reliable, and efficient systems goes beyond just writing code—it requires a deep well of experience, the ability to make tradeoffs, engage in stakeholder discussions, and wield sound technical judgment.
This necessity is why system design holds a pivotal place in technical interviews. It’s not merely about arriving at the correct answer but demonstrating how you think, unravel complexity, and justify decisions. For many engineers, preparing for this aspect of interviews is particularly challenging because it demands both technical depth and structured communication.
Fortunately, numerous open-source resources are readily available to assist. From comprehensive guides and collections of interview questions to visual explainers and specialized guides for mobile and front-end system design, these GitHub repositories have become invaluable aids, helping candidates to prepare more effectively and secure jobs sooner.
In this article, we have compiled a list of 10 valuable systems design resources. These resources can enhance your understanding of the fundamentals, allow you to practice common interview questions, and build a robust framework to approach systems design interviews with confidence.

GitHub Repositories for Systems Design Interview Questions
1. A Complete Introduction to System Design
For those beginning their journey in system design interview preparation, donnemartin/system-design-primer is a highly recommended starting point. It provides more than just a list of concepts. This repository offers a structured method to tackle open-ended interview questions, covers fundamental topics, and includes real-world examples demonstrating how to reason through compromises, rather than memorizing answers.
2. Real Interview Focused Questions and Answers
If you are looking for a resource that aligns closely with interview preparation, checkcheckzz/system-design-interview is an excellent choice. It emphasizes a systematic approach to managing system design interviews within a shorter timeframe, offering practical tips, foundational systems design knowledge, product and system examples, engineering blog references, and question-centric resources.
3. Visual Explanations of Complex Systems
For visual learners, ByteByteGoHq/system-design-101 is exceptional as it explains complex systems through visuals and simple language, avoiding theoretical overload. This framework is designed to facilitate systems design interviews while making fundamental topics like protocols, APIs, databases, and architectural patterns more comprehensible, especially for beginners or anyone seeking an intuitive understanding of systems design.
4. Step-by-Step Learning of Systems Design
Those seeking a guided learning path will find karanpratapsingh/systems design to be a smart choice. It is structured around learning to design large-scale systems while preparing for interviews. Instead of presenting scattered questions, it aids in developing an understanding of distributed systems, scalability, architecture, and interview thinking in a step-by-step manner.
5. Curated System Design Resources
For those who prefer learning from a diverse collection of free materials, asishps1/superbe-system-design-ressources is an ideal repository. It compiles free resources specifically for learning systems design and preparing for interviews. Rather than a one-size-fits-all format, it offers a curated set of articles, videos, and learning paths, perfect for filling knowledge gaps and quickly reviewing topics.
6. Interview Patterns and Problem-Solving Approaches
DreamOfTheRedChamber/system-design-interviews is beneficial for those seeking a framework that extends beyond surface interview preparation. It integrates critical thinking during system design interviews with more profound technical discussions in areas like protocols, infrastructure, and architecture. The repository is built around in-depth discussions and topic-specific notes, enhancing problem-solving instincts.
7. Links and Practical Preparation Notes
For a lightweight resource that can be quickly browsed before interviews, shashank88/system_design is quite handy. It essentially serves as a curated collection of links and preparation materials for system design and open interview rounds, working well as a practical reference center rather than a linear course.
8. A Framework for Mobile Systems Design Interviews
weeeBox/mobile-system-design is exceptionally useful for candidates preparing for mobile-specific interviews. It focuses on a framework for approaching mobile system design questions for both iOS and Android roles, emphasizing thought process and communication through hands-on exercises around real-world app design scenarios.
9. Advanced Distributed Systems Resources
For those wishing to delve deeper into distributed systems, madd86/superbe-system-design offers a curated collection of articles, videos, and learning materials centered on systems design and distributed computing. It’s particularly beneficial for individuals aiming to strengthen their understanding of overall architecture, microservices, and large-scale distributed systems.
10. Interview Resources on Frontend System Design
For front-end interview preparation, greatfrontend/superbe-front-end-system-design is invaluable. Front-end system design resources are relatively scarce, and this repository fills that gap, providing resources for interview preparation and general learning, focusing on scalability, architecture, and tradeoffs from a front-end perspective.
