Your interviewer might want to know your temper rates, and an MBA degree can make it very exhausting sometimes. You will have to work and learn with your classmates of varying personalities. So, handling all the differences and stress without getting angry matters. Your answer to this question can quote a past incident that enraged you and how you quickly reversed your anger. You can say, "I do not bring emotions into work usually. However, there are times when I have lost my temper. The last time I was angry was when my friends kept faulting me constantly for a mistake that had happened in the past. But I managed to calm down and talk to them about how I had rectified the mistake and that there was no need to criticize it now politely".
