Multiple mini interviews 2018

So I have just read that the school I applied for will now be having multiple mini interviews for fall 2018 admission. These are about 10, 5 minutes interviews that will test different characteristics they want to see in you. Every session will have 2 minute prep time right before. If anybody has done or will have this type of MMI, how did you or have you prepares for them?? This isn't your standard 30 minute face to face interview but was described to me like if you're acting.
