Do Duke and Brown college interviews matter a lot in admissions?

At both Duke and Brown, the interview is a relatively small part of the application, not a make-or-break factor. For both schools, alumni conversations are mainly meant to add personal context to your file and give you a chance to show how you communicate, reflect, and engage with other people. A strong interview can help confirm the positive picture your application already presents, but it usually will not outweigh weaker grades, coursework, or core application materials.

For the student who comes across especially well in conversation, Duke may give that piece a bit more practical value simply because Duke has long used alumni interviews as one more evaluative data point when available. Even then, it is still just one part of a very holistic review. What tends to matter most is whether you sound thoughtful, grounded, and genuinely interested, not whether you deliver a polished performance.

For either school, the interview helps most at the margins. It can reinforce qualities like intellectual curiosity, warmth, maturity, and self-awareness. It can also mildly hurt if a student seems disengaged, arrogant, or unable to discuss their interests with any depth.

So yes, doing well can help, but only modestly. Think of the interview as a chance to support your application, not rescue it.
