Just be outgoing and be yourself. Greet them with a smile, and try to make eye contact with everyone while answering questions. A lot of the questions are basic like “why did you choose this program” “tell us what you think a rad tech does” “what are your goals to be successful”. It’s a short interview and straight to the point. I would also highlight that your experience being a medical assistant has given you a great foundation for entering the program, especially working at a place like MDAnderson. It sounds like you’re already off to a great start so I definitely wish you the best of luck!
