I applied through a recruiter. The process took 2 weeks. I interviewed at IBM (Houston, TX) in Apr 2016
Interview
Interview was set for 8am - didn't start until 8:30-9am. About 6-7 individuals (including me) were scheduled to interview.
Consists of 3 separate 1:1 interviews - personal, tech/reasoning, skills/job history - (can't recall exactly) the reasoning interview is basically just to see how you think and solve problems - just 1 simple question really.
I applied through an employee referral. The process took 2 days. I interviewed at IBM (Bengaluru) in Jan 2013
Interview
Interview process was not that lengthy. It took only 2 days for me to get the offer. First round was aptitude, followed by email writing then Group Discussion and finally face 2 face interview along with HR.
I applied online. The process took 2 months. I interviewed at IBM (San Francisco, CA) in Jan 2012
Interview
Very smooth, they were all professionals, the questions were on spot. They were also friendly and tried to clarify the questions. I was not stressed at all. They wanted to get to know their future collegue as expected and I was not intimidated with personal questions
