IBM Software Developer interview questions

There was 4 rounds of interview with a Written test, English proficiency test, Group discussion, final interview. Questions about C and C++, brain teaser. What would you do if you got stuck in a place with no transportation

I was referred by my Uncle, who works for IBM. I would assume this allowed me to skip a step or two, but I know it at least short-listed me. I received an email from one of the managers who schedule a phone interview. The phone interview consisted of two parts: the first was with a group of managers who talked about the me as a person, why I chose the school I did, some of my background, mostly just general personality questions. They then left the room and brought in a group of techs. The tech group asked more about my programming experience and some of the programs and projects I had listed on my resume. Overall the interview took about 1:30, and ended on good terms. I heard back quickly about moving on to the next part of the process, and I expect to have the official offer within a week.
