It was very easy. The questions asked were logical and fewer content-based. You just need to practice mental ability and problem-solving skills. They asked about myself and my family, which was not an issue, but I was wondering why.

There were 3 rounds. All of them were technical rounds, and the last round was HR. They were asking questions mostly from dynamic programming and giving very little time to solve them.

It's not that difficult. You just need to look sharp, be confident, and answer the questions correctly. Don't be nervous; that annoys the interviewer. Just be confident. Even if you don't know something, just say whatever you know, but confidently.
