Then, purchase the eBook legally. You can highlight, copy small snippets, and store your own interpretations on GitHub. This is fully legal and far more effective than a stolen PDF.
Get the paperback or Kindle edition of Volume 2 from Amazon. The Kindle version is a PDF-equivalent (readable on any device). Cost: ~$30-40. Compare that to your hourly rate – it’s 30 minutes of work.

GitHub is a platform for open-source code. Commercial books like Alex Xu's are protected by copyright. While developers often upload PDFs to personal repositories, these are violations of GitHub’s DMCA policies and are frequently taken down.
What "Verified" usually means in this context:
Occasionally, instructors upload partial chapters under fair use for teaching. Look for repos with a LICENSE file (MIT, CC BY-NC) and clear attribution to Alex Xu. These are "verified" in the sense that they are legal and safe.
System Design Interview – Volume 2 by Alex Xu provides an indispensable conceptual foundation. Verified GitHub repositories enhance the learning experience by adding code, simulations, and community updates. Candidates should use both, prioritizing GitHub content that explicitly references Volume 2 and shows recent maintenance.
Alex Xu and the ByteByteGo team have released official "sample chapters" or free excerpts on their website and occasionally on GitHub as promotional material. These are the only verified free PDFs available, and they typically contain only the preface or a single chapter.
