Instead, buy the book, use GitHub for supplements, and walk into your interview with confidence—and a clean conscience.
Each chapter focuses on a single enterprise-grade system. Instead of giving a generic overview, Xu walks through the exact API designs, database schemas, and data flows required to make these systems function under immense traffic. Key System Design Patterns in Volume 2

The existence of these GitHub repositories does not mean one must use them. Legitimate low-cost and no-cost alternatives abound. First, the book is available on Amazon Kindle, Google Play Books, and the publisher’s website for roughly $30–$40—a fraction of a single technical interview’s potential salary bump. Second, many public libraries offer digital lending via apps like Hoopla or Libby; if they lack Xu’s Volume 2, a purchase request is often honored. Third, Xu himself has published extensive free summaries, sample chapters, and YouTube walkthroughs that cover 80% of the core concepts.
