I agree with the wise folks above, but I give interviewers the benefit of the doubt. I suspect, OP, that your child knocked it out of the park on the interview. But the interview is only one part of the whole application, so the real question is whether the great interview, combined with a transcript, SSAT, essays, recs, talents, FA status, etc. create an applicant who will fit into the school 's fabric for the upcoming year.
