Calculate the Daily Active Users (DAU), Read/Write ratios, required storage capacity per year, and network bandwidth. 2. High-Level Architecture Design (10-15 Minutes)
What are the system constraints? Focus on Availability vs. Consistency (CAP Theorem), Scalability, and Latency targets.
If you have a PDF from 2021, cross-reference these three. If the document explains them clearly, it is the real deal. hacking the system design interview pdf download 2021
Step 5: Deep Dive into BottlenecksThis is where you "hack" the interview. Identify potential points of failure. What happens if the database gets too slow? What if a server goes down? Explain how you would use tools like message queues (Kafka/RabbitMQ) for asynchronous processing or how you would implement database sharding to handle massive writes.
