2. Can you explain the concept of Object-Oriented Programming (OOP) and its principles?

Understanding OOP is crucial for software development, and this question tests your foundational knowledge.

How to Answer

Briefly define OOP and discuss its four main principles: encapsulation, inheritance, polymorphism, and abstraction. Provide a practical example of how you’ve applied these principles.

Example

“Object-Oriented Programming is a programming paradigm based on the concept of 'objects', which can contain data and code. The four main principles are encapsulation, which restricts access to certain components; inheritance, which allows a new class to inherit properties from an existing class; polymorphism, which enables methods to do different things based on the object; and abstraction, which simplifies complex reality by modeling classes based on the essential properties.”

3. Describe your experience with database management systems. Which ones have you used?

This question evaluates your familiarity with databases, which is essential for most software engineering roles.
