I applied through college or university. The process took 3 days. I interviewed at Tata Consultancy Services (Farīdābād, Haryana) in Oct 2017
Interview
The interview process went pretty smoothly. It was a campus recruitment process so 1st round was the online test which TCS has started conducting. It had coding plus general apti questions. This test was followed by 3 rounds of interview. In 1st round questions were more related to electronics me being an electronics student plus basic c. In 2nd round and 3rd round , they were hr rounds where questions such as where do u see yourself in 5 years and why do u want to move into IT being an electronics student were asked. overall interview went smoothly for me.

Interview
I was at the time when the company was hiring a huge number of students. If you clear written test, you almost got the job. If you have a good percentage you got the job unless you are extremely unlucky to have interviewed by a tough interviewer.
