I was referred by a friend. The first round was a telephonic round where the interviewer asked me a simple code and inquired about my background. After clearing the telephonic round, I was asked to come onsite for three back-to-back interviews.

The first interviewer asked me some basic questions and presented two coding problems. He was continuously interacting with me during the problem-solving, which was positive.

The second interviewer didn't seem to have any interest in the interview. He gave me a problem and sat in his chair typing something. He neither interacted with me nor reviewed the problem. It was the worst interview I have ever faced. IBM should not allow such people to conduct interviews.

The third interviewer was a fresh graduate who himself was not sure about what he was asking. Overall, the experience was horrible, with interviewers themselves not having much experience to conduct interviews. A very negative interview experience.
