TCS Digital Interview Experience

After the TCS NQT test, interviews were conducted at their offices. My interview went for around 60 mins. After introducing myself they asked me to tell them something which is not present in my resume. They asked about my favorite subjects and also about the subjects which I would learn in the current semester and then the actual interview started.

They usually conduct three rounds(technical+HR+Managerial)

The technical interview covered a wide range of topics like Object Oriented Programming, Data Structures, Java, C, C++, etc The following questions were asked of me in the technical round:
