我在系统设计面试中屡屡失败，尽管我在LeetCode上表现出色。问题不在于知识……而在于结构。资源分散在各处，没有清晰的学习路径，也无法追踪我是否真正涵盖了所有内容。因此，我建立了devwithsal.com，这是一个结构化的学习路线图，涵盖20个主题，按正确的学习顺序组织：基础 → 核心构建模块 → 设计模式 → 完整系统设计每个主题都有针对面试情境的深入解释、精心挑选的资源，以及一个自我评估问题，以测试真正的理解，而不是被动阅读。前三个主题免费： https://devwithsal.com欢迎讨论内容或方法。

I kept failing system design interviews despite being strong at LeetCodeThe problem wasn't knowledge... It was structureResources were scattered everywhere with no clear learning path and no way to track whether I was actually covering everythingSo I built devwithsal.com, a structured roadmap of 20 topics organized in the right learning order:Foundations → Core Building Blocks → Design Patterns → Full System DesignsEach topic has a deep explanation written for interview contexts, curated resources, and a self-assessment question to test real understanding rather than passive readingFirst 3 topics free: https://devwithsal.comHappy to discuss the content or the approach
