I applied through college or university. The process took 1 day. I interviewed at Tata Consultancy Services (Calcutta) in Jan 2010
Interview
I got in TCS from campus interview 3 years ago.
1. First you have to clear one aptitude test which contains Maths, English and Analogical Skill.
2. If you clear it you have to five a face to face technical interview. They asked you question from basic computer and language you know (Mostly from C, and if you know C++ or Java).
3. Though there is an HR interview round. But for my case that round has not happened.
I interviewed at Tata Consultancy Services (Mumbai)
Interview
The interview consisted on 3 rounds. All included technical questions from resume. Just study your resume well and be ready for behavioural questions.
They would also ask some basic implementation on what your work was done and how did you implement that
There was only one interview round that combined technical, managerial, and HR discussions. The interview covered technical concepts, project experience, problem-solving, teamwork, career goals, and general HR questions in a smooth, well-organized process.
I applied in-person. I interviewed at Tata Consultancy Services (Lucknow)
Interview
Not too hard. Basic programming questions. Prepare the resume properly. Data structures and algorithms . The HR interview focus on your strength and weakness. Overall it was not too difficult.
