TCS visited my campus which is guru nanak dev university amritsar on 12 dec 2010 . first there was an aptitude test n those who cleared it were called for the interview .
The interview consisted of two rounds :
1 : technical
2: HR
The technical round concentrated upon the subjects of your interest (mainly data structure and dbms for comp science students ) . Also questions based on one of major programming languages . This round was good . the interviewer was quite cool . tcs mainly focuses on your basics . make sure your basics are strong .
Once u clear the technical round u r called for HR interview . itcs only a formality . 99% of students get selected in HR . Be confident and cool . All the best .
