system design remains a critical skill in technical interviews because it tests how candidates break down complexity and justify trade-offs. even as ai generates more code, designing scalable and reliable systems requires experience and structured thinking. many engineers find this part of interview preparation challenging due to the need for both technical depth and clear communication.
the article lists 10 github repositories that help with system design interview preparation. donnemartin/system-design-primer offers a structured primer with core topics and worked examples. checkcheckzz/system-design-interview focuses on practical interview questions and tips. bytebytegohq/system-design-101 uses visuals to explain complex systems. karanpratapsingh/system-design provides a step-by-step learning path. ashishps1/awesome-system-design-resources curates free articles and videos. dreamoftheredchamber/system-design-interviews blends interview prep with deeper technical discussions. shashank88/system_design is a lightweight collection of revision links. weeebox/mobile-system-design targets mobile engineers with a framework for ios and android. madd86/awesome-system-design covers advanced distributed systems. greatfrontend/awesome-front-end-system-design addresses the rarer frontend system design niche.
each repository suits different needs, from beginners seeking a comprehensive primer to advanced learners exploring distributed systems. visual learners may prefer bytebytegohq, while mobile or frontend engineers can find specialized resources. the collection helps candidates build a better framework for approaching open-ended design questions with confidence.
why it matters: these resources help data scientists and engineers prepare for system design interviews, which are common in technical roles and require reasoning about scalable architectures.
