it was during the campus placements that TCS visited our college...the procedure was an aptitude test, followed by technical interview, followed by managerial interview and finally HR interview. The aptitude test consisted on 2 sections- mathematics and verbal...the question were logic based in maths section and in verbal section the questions tested how good are you at understanding written matter..it was easy...then came the all important technical round after i cleared the apti test...i was asked questions on all computer science topics like C,C++,JAVA, operating systems, networks, databases...most of the questions were testing my concepts...after clearing that we had manegerial round of interview where a senior member of the company asked me to write a function for calculating LCM using recursion..thats simple...finally after clearing that round, i had the HR round which was a mere formality...so guys this was my experience.
