In Tata Consultancy Services (TCS), the interview process typically involves multiple stages, depending on the role you are applying for. Here's a breakdown of the general process, particularly for technical roles like software development: 1. Application and Screening You submit your resume and application online or through campus recruitment. The initial screening includes verifying your eligibility based on academic qualifications and skills. 2.

The interviewer might also ask situational or problem-solving questions to assess your analytical abilities. 4. Managerial Interview In some cases, there's an additional managerial round to evaluate your approach to teamwork, leadership, and handling challenges in real-world scenarios. 5. HR Interview The final stage assesses your communication skills, cultural fit, and alignment with the company's values.
