Description

Object-Oriented Programming Interview Handbook is a practical guide for mastering OOP design interviews through clear modeling and structured thinking. Object-oriented interviews test more than definitions—they evaluate how you design classes, manage dependencies, apply SOLID principles, and build systems that remain maintainable as they grow.

This handbook contains 160 carefully selected interview questions covering core OOP principles, class design, inheritance and polymorphism, design patterns, dependency management, testing, and advanced real-world modeling scenarios.

Each question is designed to help you think like a professional engineer, justify design decisions, and communicate object models clearly and confidently. The focus is on principles that apply across languages and frameworks.

This book is ideal for students, backend developers, full-stack engineers, and experienced programmers preparing for object-oriented design interviews.
