System Design Interview Handbook

Ebook Description

System Design Interview Handbook is a practical guide for mastering system design interviews through structured thinking and clear decision-making. System design interviews are open-ended by nature, and interviewers evaluate how candidates reason about scale, reliability, trade-offs, and real-world constraints rather than how many technologies they can name.

This book contains 160 carefully curated system design interview questions covering requirements analysis, capacity estimation, high-level architecture, databases and storage, caching and performance, scalability and reliability, messaging systems, security, observability, and production readiness.

Each question is designed to help you think systematically, ask the right clarifying questions, justify architectural choices, and communicate designs confidently. The focus is on principles and reasoning that apply across companies, technologies, and domains.

This book is ideal for mid-level to senior software engineers, backend and full-stack developers, and anyone preparing for system design interviews. By the end, you will be able to approach complex design problems with confidence, structure, and a production-ready mindset.
