The TCS interview process typically starts with an online assessment conducted through TCS iON or NQT, which tests candidates on quantitative aptitude, logical reasoning, verbal ability, and programming skills depending on the role. Candidates who clear the test move on to a technical interview where fundamentals of core subjects, programming concepts, and project work are discussed in detail. This is followed by a managerial interview that evaluates problem-solving ability, teamwork, communication skills, and how the candidate handles real-life work situations. The final stage is the HR interview, which focuses on cultural fit, career goals, willingness to relocate, and basic HR-related questions before the final selection.
