"The interview is an opportunity for applicants to express themselves to the admissions committee. Interviewers are not looking for any specific information about the applicant; rather they seek to have a general conversation about the applicant’s thoughts and interests. Each interview will be unique based on the interviewer and the applicant, but some topics that may come up include: academic interests, extracurricular activities, summer experiences, family background, future plans, and exposure to Georgetown. ...
In addition, students should view the interview as an opportunity to express anything they think important the admissions committee know about them that they did not fully articulate in the application. Finally, students should use the interview to learn more about Georgetown and the Georgetown community from the perspective of an alumnus. An interview report will be submitted and becomes part of the admissions file. While the interview report is used as part of the admissions committee’s consideration process, it rarely “makes or breaks” an application, and much more often than not it works in the applicant’s favor."
Who conducts the interview?
"The Alumni Admissions Program (AAP) is a volunteer network of over 4,000 Georgetown alumni who interview all undergraduate applicants around the world. The AAP is divided into over 200 regional committees and has been interviewing students for over 35 years. AAP interviewers may be alumni of any school at Georgetown, graduate or undergraduate, and they range in experience from the most recent graduates to alumni of the 1950’s. They are a dedicated group who are there to help the admissions committee learn more about Georgetown’s applicants as individuals."
