How important is an interview?

<p>I have most of the application done except for the "Why do you want to study engineering at Duke?" question. I can get that done this week and go for the interview or take my time and now make the Dec.10 deadline for an interview. Do interviews play a large roll in the admissions process?</p>

<p>I had the same problem but decided to go with both by staying up really late the night of Dec 10 (last night) to finish my why duke.
