🧠 Top 7 System Design Tips for Coding Interviews 🏗️💻

1️⃣ Clarify the Requirements
⦁ Ask: What features are must-haves?
⦁ Define inputs, outputs, users, scale.

2️⃣ Define System Constraints Early
⦁ Expected users per day?
⦁ Read vs write-heavy?
⦁ Latency, availability, storage?

3️⃣ Break Down the Architecture
⦁ Frontend → Backend → Database
⦁ Talk about APIs, request flow, and layers.

4️⃣ Use Diagrams While Explaining
⦁ Sketch: Load balancer, app servers, DBs
⦁ Use simple boxes & arrows to show flow

5️⃣ Discuss Scalability
⦁ Horizontal scaling vs vertical
⦁ Use of caching (Redis), CDN, sharding

6️⃣ Talk About Trade-offs
⦁ SQL vs NoSQL
⦁ Monolith vs microservices
⦁ CAP theorem: choose consistency, availability, or partition tolerance

7️⃣ Mention Bottlenecks & Optimizations
⦁ Caching hot data
⦁ Rate limiting
⦁ Queue for async processing (like RabbitMQ)

💡 Pro Tip: Practice explaining well-known systems (e.g. Instagram, WhatsApp, URL shortener) out loud!
