I appeared for a TCS interview for the digital role, which lasted around 25 minutes and included both technical and HR questions. The panel started with a brief introduction and then asked about the programming language I’m most comfortable with—I chose Java. I was asked to write code for matrix multiplication and demonstrate class inheritance. They also asked for an SQL update query and a small snippet to show user-defined exceptions and exception handling. I discussed types of exceptions like IndexError, ValueError, and ZeroDivisionError. They inquired whether my project link was accessible online, followed by personal questions like where I live, my university, and my hobbies. I wrapped up the interview by sharing feedback. A key suggestion they gave was to focus on mastering one programming language and sticking to one strong tech stack rather than juggling multiple ones. The panel was friendly and mostly focused on fundamentals and clarity of concepts.
