HR reached out to me through WhatsApp and they will provide the interview agenda and some interview preparatory tips before the interview day. The interview started with a group case discussion, which I think being clear and confident about your answers is extremely important in this case. We were given about 30 minutes to discuss the case and we had 15 minutes to present. After that, we had 2 rounds of casual one-to-one chat. There was a surprise after the assessment ended!! HR updated me on the interview process after two working days. Although I did not get the offer, overall it was an insightful and pleasant interview :)
