I applied through university. The process took 2 days. I interviewed at Tata Consultancy Services (Thiruvananthapuram) in Oct 2014
Interview
You must pass the Aptitude Test, which, in my case, was conducted at my college, they would let you know that evening itself, that if you have passed or not.
Then there would be a technical Interview
An HR round
An MR round
First 2 rounds are the hardest,
