System Design Interview
Turn interview anxiety into architect-level clarity. This practical playbook gives you a proven framework, real-world patterns, and interview-ready designs—so you can communicate tradeoffs with confidence and build systems that scale.
Who this book is for
• Mid/Senior Developers leveling up to Staff/Architect roles
• Interview candidates targeting Big Tech, startups, and high-scale teams
• Bootcamp/CS grads who want a repeatable, time-boxed approach
• Tech leads & founders designing reliable, cost-aware systems
What you’ll be able to do
• Think in systems, not features: Move confidently across user, service, and data layers
• Answer under pressure: Use a 4-Step Framework to gather requirements, estimate load, design high-level architecture, and deep-dive on bottlenecks
• Scale with intent: Apply sharding, consistent hashing, caching hierarchies, queues, and backpressure to survive peak traffic
• Design for reliability: SLAs/SLOs, replication, failover, graceful degradation, and multi-region thinking
• Optimize performance & cost: Balance latency vs throughput, UX vs spend with cost-aware patterns
• Communicate like an architect: Follow the interview checklist to show structure, judgment, and tradeoff literacy
Inside the book (highlights)
• Foundations that matter: OLTP vs OLAP, event- vs request-driven, CAP theorem, SLA/SLO/SLI, latency vs throughput, rate limiting & throttling
• Architecture toolbox: Monoliths vs microservices, service discovery, API gateways, REST & GraphQL, pagination, versioning, retries, idempotency
• Data & storage: SQL/NoSQL/NewSQL, replication & sharding, indexing & search, object storage, data lakes/warehouses, hot-partition avoidance
• Infra & DevOps: CDNs, DNS, L4/L7 load balancing, containers & orchestration, CI/CD, blue/green & canary, autoscaling, multi-region & multi-cloud
• Observability & security: Metrics, logs, tracing, health checks & alerting, OAuth2/JWT, encryption, secret management, Zero Trust
• Back-of-the-envelope estimates: Quick, defensible math for QPS, storage, and throughput to justify your design
Real systems you’ll design (interview-ready)
URL Shortener, Instagram-style feeds, WhatsApp messaging, Twitter/X timelines, Uber-like matching, YouTube uploads/streaming, Cloud Storage (S3-like), E-commerce, Payments & Digital Wallet, Email service, Search Autocomplete, Leaderboards, Web Crawler, Hotel Booking Engine—and more. Each includes requirements, APIs, components, bottlenecks, tradeoffs, scaling, and architecture flow.
Deep dives & case studies
Instagram Reels, Netflix global infrastructure, cost-aware architecture, multi-tenancy, global multi-region setups.
Interview vs. Real-World
Every topic contrasts “System Design in Interviews” vs “on the Job” so you can defend choices under constraints and ship pragmatically.
Fast study plan (4 weeks)
Week 1: Core concepts, CAP, SLA/SLO/SLI, BOTE
Week 2: Databases, caching, queues, API design, reliability
Week 3: Build 6–8 systems end-to-end; practice tradeoffs aloud
Week 4: Full mock interviews using the checklist & metrics playbook
