Company came to our undergraduate institution looking to hire interns. There was a technical aptitude test. After 2 weeks selected candidates were called for on site interviews. 3 rounds total, shortlisting happening every round. 1 was purely technical, 1 HR and the final one a mix

The first interview was a group interview, where you had to play a small game together, which mainly tested your cooperation ability. The second interview was a resume interview, where the questions were based on your past experience. It was very intense, and the interviewer would keep asking you until you ran out of words.
