Not every college requires an interview. But when one is offered, take it. Skipping an optional interview at a school that offers them can signal lack of interest. Showing up, prepared and genuine, is a meaningful positive signal. And unlike essays, the interview lets you actually have a conversation. That's a rare thing in an otherwise one-sided application process.
Types of College Interviews
Most college interviews fall into one of three categories. Alumni interviews are the most common. A local graduate volunteers their time to meet with applicants, usually off-campus over coffee. These are lower-stakes than on-campus interviews, but they still matter and the alumni do submit reports. Admissions officer interviews happen on campus or virtually and carry more direct weight. Peer or student interviews are offered by some schools (Johns Hopkins, Dartmouth) and conducted by current students rather than staff.
The format changes the preparation slightly but the fundamentals are the same across all three.
Before the Interview: Do the Work
The single most common interview mistake is being unable to answer "Why this school?" with any real specificity. Generic answers kill interviews. "I've always wanted to go to a school with a great academic reputation and a strong sense of community" could describe 500 schools. It tells your interviewer nothing useful about why you want to be there specifically.
Before your interview, research three to five specific things about the school that genuinely interest you. A professor's research you've read about. A program or center that doesn't exist elsewhere. A course that looks unlike anything you've seen. A student publication, a lab, an initiative. Specificity signals genuine interest. Generic compliments signal that you did 10 minutes of research.
Common Interview Questions and How to Think About Them
Don't recite your resume. Tell a story. Pick two or three things that matter most to you and connect them. "I've spent the last three years building apps and arguing about AI ethics. Those two things sound different but they're connected by..."
Pick something real, not performative. What did it actually feel like? What did you do? What do you think differently about now? Don't skip to the lesson. Spend time in the actual experience first.
This isn't a trap. Say the true thing. Interviewers are not hoping you'll say something impressive. They're hoping you'll say something real. "I make weird playlists and cook elaborate meals for my family on Sundays" is a better answer than "I enjoy reading literature and staying informed about current events."
See above. Be specific. Name the actual thing. Not the vibes. If you visited campus and something struck you, say what it was. If a faculty member's research connects to something you care about, say how.
Always have questions. Good ones. Not "what's the social scene like?" Ask about something specific to your interviewer's experience at the school. Ask something you actually want to know. The quality of your questions reveals how you think.
Practical Logistics
Dress like you're going to a business casual meeting, not a job interview at a law firm and not school clothes either. Middle ground. Be on time or slightly early. If it's virtual, test your technology the night before, find a quiet space with good lighting, and close your other browser tabs. Bring a copy of your resume or activity list in case it comes up, but don't lead with it.
Send a brief thank-you email within 24 hours. Keep it short and genuine. Reference something specific from the conversation. Three sentences is fine. The point is to demonstrate the same care and follow-through you'd want to show in college.
What sinks interviews
Talking too much. Giving rehearsed-sounding answers that have no texture or spontaneity. Pulling out your phone. Saying you're interested in a school for reasons that are clearly about its ranking rather than anything specific about the place. Not asking any questions. All of these happen more than you'd think, and all of them are avoidable.
