Arrive at your interview prepared with questions for the interviewers at the University of Colorado. Avoid any questions about the locale, college life, or anything informal. Asking too much about the culture, social life, and extra-curricular activities may cause you to appear interested in their university for all the wrong reasons. Focus the majority of your questions on academically related subjects.
If you are unsure what questions to ask, write down anything that generates a question mark or which you feel needs clarification while conducting your research on the University of Colorado. This will showcase the breadth of your research and present you as fully prepared for your interview. It will also inform them of the type of future alumnus/alumnae you'll prove to be.
