Foundational Object-Oriented Programming (OOP) for Technical Interviews

Understanding Object-Oriented Programming (OOP) is crucial for writing maintainable software and passing technical interviews, yet many developers struggle to explain its core concepts clearly. This text-based course demystifies OOP, breaking down abstract theory into practical, easily digestible explanations. You will transition from writing disorganized procedural code to designing clean, modular, and reusable object-oriented systems. By mastering these core principles, you will gain the confidence to articulate your design decisions during coding interviews and team discussions. What you'll learn: - Understand the foundational definitions of classes, objects, state, and behavior. - Explain the four pillars of OOP: encapsulation, inheritance, polymorphism, and abstraction. - Apply modern design principles such as composition over inheritance to write flexible code. - Analyze common technical interview questions about OOP design patterns and relationships. - Identify code smells and refactor tightly coupled code into clean, modular structures. The course begins with basic terminology and foundational definitions before guiding you through real-world scenarios, design principles, and interview-focused conceptual questions. You will learn entirely through clear written explanations and illustrative code snippets. This course is designed for beginner programmers, self-taught developers, and computer science students preparing for technical job interviews. No advanced programming experience is required.
