I would say take this chance to present yourself in the most unique way possible, as yourself. This is your one chance to showcase who you are in person, not through some words in your application, you have to present the real you. While you’re there try to smile, warm up to the interviewer, give a positive aura to show that you’d be a good fit for Barnard. Also, be honest, I personally believe interviewers can smell lies and fakeness a mile away.
