IBM Intern interview questions

On campus interview followed by a phone interview. The campus interview was roughly 30 min. We were give a set of data prior to the interview. At the interview we were asked about the data, and what we could infer. In addition, there were skills based questions gauging our understanding of the foundation of electronics. Overall, the interview wasn't to nerve raking, and some of the puzzle questions were actually a bit of fun.

Applied through college/university. They conducted a Hackathon. A full day event. Candidates were chosen based on the product developed, idea etc. Hackathon was on a smaller scale. It totally depended on what you tried to develop and your approach.
