Interview round 1: Technical interview
This is the most challenging stage of the hiring process, so do your best to prepare for it. The focus of the entire interview process will be on your technical knowledge, biography, and primary projects.
The technical round of the TCS interview which is face to face consists of questions designed to assess the candidate's knowledge of data structures and algorithms, database management systems, operating systems, networking, object-oriented programming ideas, and a programming language of your choice. There's a considerable chance you'll be asked to write some code on pen and paper.
Interview round 2: Managerial round
The managerial round is handled by a panel of senior members. This is also a face-to-face interview round. This round may consist entirely of technical questions or a combination of technical and managerial questions. The majority of the questions are based on the profile for which you are being interviewed. You should be up to date on any new technologies or software required for that position. You may also be asked questions based on your actions to assess your thinking style. You could be put under pressure to see how you react. Your CV's achievements may be questioned, and you may have to defend them. You may be questioned on your previous working experiences, about your objectives, motivations for joining TCS, and other similar topics.
The panel will assess your corporate culture fit, attitude, soft skills, desired career advancement, and other factors in this round.
You might also be asked generic questions about your work experience, college degree, specialty, desire to relocate, and so on. In any event, regardless of the route the interview takes, always be gracious. The interview panel aims to force you to step outside of your comfort zone. Maintain your composure and respond to the questions that you are familiar with. If the answer is unknown, don't give up; instead, try it with what you know.
Interview round 3: HR round
Expect questions about work experience, education, interests, and family background, in addition to the standard HR questions about strengths and weaknesses, reasons for applying to the company, why you should be hired, and so on. They can also ask questions about TCS - when it was formed, its objectives, values, organizational structure, and so on.
