🎯 𝑾𝒉𝒚 𝑶𝑶𝑷 𝒊𝒔 𝒂 𝑴𝒖𝒔𝒕-𝑯𝒂𝒗𝒆 𝑺𝒌𝒊𝒍𝒍 𝒇𝒐𝒓 𝑰𝒏𝒕𝒆𝒓𝒗𝒊𝒆𝒘𝒔. Object-oriented programming (OOP) is essential for writing clean, scalable, and reusable code. Here’s why it’s a game-changer for technical interviews, especially at MNCs: 1️⃣ Backbone of Programming: Core to languages like Java and Python and frameworks like React. 2️⃣ Scalable Code: Principles like inheritance and encapsulation make your code modular. 3️⃣ Interview Favourite: OOP questions are a staple—know concepts and real-world applications. 4️⃣ Real-World Design: Ideal for breaking complex problems into reusable components. 5️⃣ Universal Use: OOP is applicable across domains, from the backend to apps.
