I applied through a college or university.

It went really smoothly. Each interview was one-on-one, and they were really friendly and helpful, which made me feel comfortable and think better too. They helped me out with hints when I got stuck at places.

There were three rounds of interviews, all of which were technical. The last round was more difficult since they asked questions about yourself to determine culture fit. That was the deciding round, and even people who were good enough and answered all technical questions correctly found it difficult to face the last one. All the rounds happened soon one after another with little time in between, which made the whole process faster.
