YES! Not all universities require an interview, however, even if it is optional, do the interview. The interview gives the university the opportunity to put a face and personality to an application, and it gives students the opportunity to share anything that they may not have on the application. If you put in enough practice, it’s a win-win situation.
Most interviews have to be scheduled by late November or December so it’s important to look into those deadlines.
If location is an issue and you cannot go in for an interview at the university, you’ll have the option of interviewing with an alumnus in your area or conducting an interview via Skype. Options vary per university.
