An unexpected thing happened during the case study: Two of our group members(one of them was me) were asked to argue and prove that He/She is the better person for the job. We were told that only the one who is able to convince the other will be given an offer.
We kept our composure and did not fight much. Both of us got selected to the next round. They expected the team members to be united and not fight for personal gains. This might not be the case always.
