Just contribute a data, my son didn’t get the interview and was rejected. He was admitted into Princeton and Cornell. None of students in our school (located in central NJ) got interview nor got in. So I believe Harvard AO decided in very early to not pick up any kids from our school this year.
Some background: Top colleges like Harvard/Yale/MIT, etc admitted one student from our school in every couple of years. Last student Yale admitted was in 7 years ago, MIT 3 years ago. Harvard admitted one student last year, but he chose to attend Stanford. Princeton usually admits couple students every years, and Cornell 5-10 kids every years. Brown/Dartmouth/Columbia are very similar as Harvard. UPenn is more random.
