Object Oriented Programming Interview Questions: Prepare for Your Coding Interview

ByNila

To ace your coding interview, you should be well-versed in Object Oriented Programming (OOP). Brush up on the four key principles: encapsulation, inheritance, polymorphism, and abstraction. Understand how encapsulation enhances security, and how inheritance fosters code reusability. Get familiar with polymorphism's method overloading and overriding features. Recognizing design patterns like Singleton and Factory can set you apart. Keep these concepts in mind, and there's much more to explore that can strengthen your skills even further.
