I applied through college or university. The process took 3 days. I interviewed at IBM (Greater Noida). I applied through college. The drive held in Sharda University. First there was an Online Test(Aptitude+Business Development). [Solve previous years questions of IBM test to qualify for interview]. Result was declared within 2 hrs. Then on the 2nd day interview process took place. There were 9 panels for the interview process. On the first day they asked easy questions but on 2nd day the started asking technical questions too(maybe because they selected lot of students on the first day). Be confident in front of them is the key to get selected.
