I remember 3 years ago Tcs came to our college for hiring purpose. I was the topper in our college, so got a chance to directly give the interview. So i will tell you the first round of my technical interview. They asked introduction thn current project , fav subject, swapping without using 3rd variable , pattern draw, questions from data structure, SQL queries, join in sql. There were 2 interviewer one was checking technical skill and another one managerial skill. The interview took approximately 1 hour. After 3 hours of interview result came. And I went for Hr interview , hr was very cool. He asked do u have fb account :p Do you left tcs once you will get married. Why you want to join our company,Tell me about your family. In this they mainly check your confidence. As my english was not so good. So he said to me improve it before joining tcs. So i understood that I got selected. The final result came at 4 o clock early morning. We all were waiting n didn't sleep whole night. After knowing the result we all were very happy and remain awake the whole day.
