A recurring theme across GitHub study guides inspired by Xu is the Four-Step Framework
, which is essential for a structured interview performance: Understand the Problem and Scope:
Spend the first 5–10 minutes asking clarifying questions. Define the DAU (Daily Active Users), technical constraints, and "must-have" features. Proposed High-Level Design:
Draw the end-to-end flow. Don't get bogged down in the weeds yet; focus on the API endpoints and the movement of data. Design Deep Dive:
This is where Volume 2 shines. You pick 2–3 core components (e.g., the proximity service in a map app) and discuss data structures, bottlenecks, and failure modes.
Summarize the trade-offs. No system is perfect; being able to identify where yours might fail is a sign of seniority. Utilizing GitHub Resources

If Proximity Service is the foundation, Nearby Friends is the penthouse. This problem adds a critical layer of complexity: Real-time updates.
Ask any Indian “What’s for dinner?” and you’ll hear a story. Food in India is deeply regional, seasonal, and personal. A Tamil Brahmin’s sambar tastes nothing like a Punjabi’s dal makhani. Yet, there’s a shared language: thali (a platter with small portions of multiple dishes), the importance of eating with hands, and the belief that food nourishes not just the body but the mind and spirit.
Street food culture—pani puri, vada pav, dosa—is democracy in action. A CEO and a rickshaw driver might stand side by side at the same cart, crunching into the same spicy bite.
