Next up, you'll need to know about object-oriented programming (OOP) concepts like inheritance, polymorphism, and encapsulation. It's like building a LEGO castle, except instead of blocks, you're using classes and objects. And just like LEGO, it's all about creating a solid foundation and building on top of it.
So, you might get asked about the difference between inheritance and composition. Now, I know it sounds like a mouthful, but trust me, it's not as complicated as it sounds. Just think of it like a family tree - inheritance is like a direct descendant, while composition is like a cousin twice removed.
