First a computer test then PI. All the questions were based on coding. Very comfortable environment for interview. Normal paper on maths and aptitude and reasoning another paper for coding based questions.

The TCS interview process generally involves clearing an Online Assessment (aptitude, coding, email writing), followed by multiple interview rounds: a Technical Interview (core concepts, problem-solving, your projects), a Managerial/ < Behavioral Interview (leadership, handling challenges, real-world scenarios), and an HR Interview (communication, cultural fit, motivation). The number of rounds can vary, but these three are standard for evaluating technical depth, behavioral fit, and suitability for TCS's work culture.
