Perform "back-of-the-envelope" calculations for traffic and storage needs. Create High-Level Design: Map out the primary components and data flow. Design Detailed Components: Deep dive into specific bottlenecks or critical services. Interfaces & Protocols:
By spending the first 5 minutes asking these questions, you demonstrate seniority. Senior engineers never build without specs. --- Hacking The System Design Interview Stanley Chiang Pdf
The interviewer will now probe: "What happens if our cache fails?" or "How do we handle hotspots?" This is where you demonstrate trade-off thinking. Interfaces & Protocols: By spending the first 5

Most candidates fail here. They hear "design Twitter" and immediately draw boxes. The senior engineer hears: "What kind of Twitter? What's the read-to-write ratio? Are we optimizing for latency or consistency?"
