1) Walk me through your resume. 2) Where do you want to be/what do you want to do? (why mba?) 3) Why Columbia? 4) Columbia is known as a finance business school, why does someone with your background want to attend Columbia? (interviewer had finance background) 5) What kind of leader are you? 6) What makes you different? 7) Any questions for the interviewer?
The interviewer was very friendly as it was very conversational and it seemed like he was genuinely interested in my story. Make sure you are prepared and have a good answer to sell yourself why you want to go to Columbia over any other school.
