There is a famous "top" repository that parses Alex Xu’s volumes and cross-references them with actual LeetCode System Design questions. It creates a table: system design interview alex xu volume 2 pdf github top

This is arguably the most valuable "top" resource because it tells you exactly which coding exercise to practice after reading the theory. Why Volume 2

Example of a high-star repo structure (Volume 2 notes):

├── chapter01_whatsapp

Why Volume 2? The Evolution from "Chat" to "Deep Dive"

Volume 1 was a masterpiece of fundamentals. It taught you how to build a URL shortener (TinyURL), a chat system (WhatsApp), and a video streaming platform (YouTube). It focused on High-Level Design (HLD) : Load balancers, caching, database sharding, and CDNs.

Volume 2, however, is the sequel that nobody expected to surpass the original. Released in 2022 (updated since), Volume 2 addresses the massive feedback from the community: "The first book got me the job, but I failed the Google L5 interview because I didn't know about transactional outbox or Bloom filters."

📌 Recommendation for interview prep

Buy Volume 2 – It’s worth the investment for the depth and recent examples.
Use GitHub repos only for:
- Quick revision checklists
- Community answers to “how would you design X?”
- Anki decks
Practice whiteboarding – Don’t just read; draw the architecture.
