To follow Doktor Timo with additional unsolicited advice - this school uses the interview to see what YOU are like. If you practice canned answers, they'll know. They want to meet YOU, learn something more about YOU, and see how YOU feel and think about certain things. It's a conversation. Questions are only meant to start the conversation and to continue the conversation. You know yourself best - I said this to a lot of people last year when they were sitting outside their interviews, just take a breath - it's a conversation where you get to talk about yourself and really be honest about who you are and what you want. Try to relax. It's completely ok to be silent for a moment in order to answer something they've asked! I'll likely be buzzing around studying and what not on the 14th and 21st - so some of you are likely to bump into me telling you to breathe and you'll be fine 😉
