I applied through college or university. I interviewed at IBM (New Delhi) in Feb 2015
Interview
They had a normal test of Quant and reasoning after that test of english was there which has formal. On clearing both the steps there was an interview. It was easy and casual where HR was only interested in basic IQ and communication skills. he also asked current affairs and basic questions about project. No specific subject.

I applied through an employee referral. The process took 3 weeks. I interviewed at IBM in Sep 2015
Interview
I inquired through email after my college passed on a message that a specific team was hiring shortly after I graduated. Applied officially online. Had a short phone interview and then 2 more 30 min phone interviews within a week. Mostly they just told me about what they did. Only really asked me to tell them about myself. I asked questions and tried to be 'insightful'. They implied I was hired but I had to take an iq type test. It took awhile to get through that and the background check (although they never actually said it was a background check... Just asked details about my prior work & education). That part is all outsourced to India and was very slow and took about a week.
The iq test says you don't to prepare but I was frustrated to find I could barely remember the quadratic equation and other algebra topics you haven't used in years that were needed for the timed test. I think i did horrible, but they don't tell you how you did. Got an official offer letter from the Indian recruiting dept including bonus & relocation about a week later.
