You are asking to be chanced for schools which are so prestigious where a lot of the most excellent students still get rejected. You have excellent stats and excellent ECs, but so does everybody else that applies. All somebody can tell you is that you are qualified for admission, but there is no way to make those schools anything but reach schools.
@intellectboy It might be okay to send them a reminder email, for example, “On January 22, I received XXX email but have not yet heard back from my interviewer…” Be polite about it.
Yes, it is a miter.
