HR ROUND(10 mins)

It was a long day started at 7 in the morning and ended 10 at night. There was a long gap between rounds because there were more than 20 students shortlisted for interviews and they had to conduct each round for all of them before they released the shorlist for next round. Then we had dinner with the team and QandA session.
