To succeed, you must follow a structured framework rather than jumping straight into drawing architecture diagrams:
If designing a video streaming platform, focus on .
Namaste. 🙏
Liu uses real-world examples to demonstrate how to develop assumptions and design options. Notable case studies include: (e.g., Uber/Lyft architecture) Social Media Systems (e.g., Instagram-like image feeds) Large-scale Storage (e.g., Cloud file storage) System Design Interview Fundamentals Rylan Liu Pdf
Rylan Liu's “System Design Interview Fundamentals” is a guide structured to help software engineers navigate the unique challenges of these interviews. The book focuses not just on memorizing definitions but on applying technical knowledge to develop trade-offs and designs that impress interviewers.
Calculate the Daily Active Users (DAU), Read/Write QPS (Queries Per Second), and storage requirements for 5 years. Step 2: High-Level Architecture Design (10-15 Mins)
: Offers more than 30 technical fundamentals with a focus on applying them to real-world trade-offs rather than just providing definitions. Mock Interview Format To succeed, you must follow a structured framework
To excel in a system design interview, you must have a deep, practical understanding of fundamental distributed systems concepts. Load Balancing
: Implementing Load Balancers , Caching , and Databases (SQL vs. NoSQL).
Draw a bird's-eye view of your architecture. Outline the flow of data from the client, through the API gateway and load balancers, to the web servers, application services, and underlying databases. Define the core API endpoints (e.g., POST /v1/tweets , GET /v1/timeline ). Step 4: Detailed Deep Dive (15–20 minutes) Notable case studies include: (e
Knowing the technical fundamentals is only half the battle; you must also master the interview process itself. A key insight is that the solution is not the ultimate goal of the interview; the goal is the conversation, which should cover both breadth and depth.
