COURSE
The object-oriented programming round, answered out loud. The four pillars, classes and objects, inheritance and polymorphism, abstract classes versus interfaces, composition over inheritance, and the SOLID principles — each with in-depth full notes to learn the topic properly, a quick-revision cheat sheet, 25 explained Q&A and a rapid-fire mock, 30 predict-the-output and design problems, and a company-wise module covering what TCS, Infosys, Wipro, Accenture, Capgemini, Cognizant, HCL and product companies actually ask freshers. Language-agnostic with examples in Java, and notes on how C++ and Python differ. No multiple choice in the interview modules — every question is asked the way an interviewer asks it, and every answer gives you the words to say, the follow-up that comes next, and what NOT to say.
