I applied through college or university. The process took 1 day. I interviewed at Tata Consultancy Services (Vellore) in Sep 2017
Interview
TCS company was a mass recruitment company. After waiting for some 3 hours I got my opportunity to be interviewed. They asked us to submit all the grade sheets of Xth, XIIth and B. tech . It was fun and my interview panel members were chilled guys.
TCS NQT - Basic aptitude test. You can clear the test easily if you have prepared from indiabix.com
After the test, they call for direct interview which has technical and hr panels combined. They generally send the offer letter the next day.
