Welcome to this exciting journey! Throughout this course, you will engage in AI-roleplays to hone your technical interview skills on various software development principles, methodologies, and paradigms. Let's begin with the key principles of Object-Oriented Programming (OOP).

During a job interview, you are likely to face questions on key OOP principles such as:

• What are the key principles of object-oriented programming (OOP)?
• How do these principles enhance software design?
• Can you provide examples of each principle?

By understanding these questions, you can prepare concise yet comprehensive answers that illustrate your knowledge.

1. Encapsulation:

   • What it is: Encapsulation refers to bundling the data (attributes) and methods (functions) that operate on the data into a single unit, often a class.
   • Why it matters: This principle helps in hiding the internal state of an object from the outside world, promoting modularity and reducing code complexity.
   • Remember: Encapsulation enhances code maintainability and security by controlling access through access specifiers.

2. Abstraction:

   • What it is: Abstraction involves hiding complex implementation details and showing only the essential features and functionalities of an object.
   • Why it matters: This principle reduces complexity and allows the programmer to focus on interacting with an object at a high level.
   • Remember: Abstraction helps in the development of a more user-friendly interface.

3. Inheritance:

   • What it is: Inheritance allows a new class (child class) to inherit the properties and behaviors of an existing class (parent class).
   • It promotes code reusability and establishes a natural hierarchy among classes.
