I applied through college or university. The process took 5 days. I interviewed at Tata Consultancy Services in Sep 2013
Interview
For people with more then 8.5 CGPA, there is direct interview which is a mixture of both technical and HR. They mostly ask questions from resume and your area of interest. Don't drag answers. Just say up to the point and it'll be over within 10 minutes. If you drag without knowing the answer, they just keep asking questions from your answer.
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.
