if an interview cannot be arranged, you will not be at a disadvantage during the application process.

not only Harvard has much less interviews this year, so do other top schools.
Is that just your guess or you heard it from some reliable sources?
My sample size is small, but I heard this from people at different parts of the country applying various schools..
QUESTION: My interviewer let it slip that I was marked a high priority candidate. What does this mean for my admissions chances?
ANSWER from @T26E4, who is no longer on CC but was an alumni interviewer for Yale: Harvard does initial read thrus immediatly. Thus, they can target Likely Letter recipients. THen with the rest of high likelihood admits, they can informally ask the area alumni groups to "Yeah we know we sent you a list of fifty, but can you really make sure you cover these five?"
