My son, a graduate of Harvard University in 2021, went to look at his application for admission in accordance with FERPA and found that one of the most mentioned things in the viewing comments, about 6 times, concerned his ethnicity. He is an American born in Costa Rica.
Another thing they liked was that he worked 20 hours a week in his senior year at a popular clothing store in the mall.
However, he was also accepted to Yale, Allen, Stanford, a total of 9 of the top 11 schools, while in the other two he was on the waiting list. So it's probably safe to say that he was a reliable candidate.
