There were three rounds.

The first was the technical round, which had some good questions.

Selected candidates were called for an online interview. I was asked an extension of Kadane's algorithm that involved a circular array. I wasn't able to solve it, so I was not called for the third round.

The third round is the HR round, which was decent, as my friend told me. The interviewers were chill. They would sit quietly for the given time, so you should try to engage with them to show that you are interested in the company.

Extension of Kadane's algorithm. Circular array given.
