The Biggest Interview Mistake I Saw Wasn’t Nerves

When parents imagine a private-school interview going badly, they picture a frozen, silent child — the one who clams up and can’t get a word out. That happens, and there’s a fix for it (I’ll write about that next week). But it was not the mistake that actually cost children in the room.

The mistake that cost them was the rehearsed answer that fell apart on the first follow-up.

I saw it constantly. A child would deliver a smooth, clearly-practiced line — poised, polished, obviously prepared. Then I’d ask one small unscripted question. “Say more about that.” And there was nothing there. The performance had a script, and the script had run out.

There is a real and visible difference between a prepared child and a rehearsed one, and interviewers spot it almost instantly. A rehearsed child has memorized wording. They pattern-match your question to the answer they practiced, deliver it, and stall the moment the conversation turns somewhere they didn’t rehearse. A prepared child has done something entirely different: they’ve gotten comfortable with their own material — what they care about, a few stories, what they actually think. So when the conversation turns, they turn with it. They were never on rails; they just know a few things about themselves well enough to talk about them.

The difference isn’t how much work the family did. It’s what they practiced. Rehearsed kids practiced a script. Prepared kids practiced knowing themselves.

You can usually see rehearsal by the first follow-up. The eyes go up and to the side — not thinking, retrieving. An answer arrives that doesn’t quite fit the question, because the child heard a keyword and delivered a memorized block. The cadence flattens into recitation. And the surest tell of all: the language gets too old for the child. A ten-year-old does not naturally say “I’m passionate about fostering collaborative environments.” When I heard that, I knew exactly what had happened at the kitchen table.

The cleanest test I had was simple: I’d poke the polished answer. “Tell me more about that.” A rehearsed child stalls or restarts from the top. A prepared child just keeps talking — maybe knocked off the rails, but still conversational, because there were never rails to begin with, just a thing they genuinely know about.

So if you take one thing into your own prep this fall, let it be this: prepare your child, don’t script them. The instinct to hand a nervous kid a good answer to lean on is loving and completely understandable. But a memorized answer is a liability the moment the interviewer gets curious — and getting curious is the interviewer’s whole job. A child who simply knows what they like, and has talked about it out loud a few times with you, can carry a real conversation all day. That’s the child you’re aiming for.

Next week: the frozen kid — the one parents fear most — and the single sentence that turns a scary silence into a normal pause.
