Do early submissions get reviewed BEFORE the actual closing date? That's the clear implication from what I've read elsewhere on this thread, because it's stated "there is more time to review early applications"
In my case, I submitted (initially) soon after the applications were opened, and have been editing, proof reading, clarifying generally and improving on it, and re-submitting right up to this evening - the evening of the closing date. So there are quite possibly at least 30 different iterations of my application. My first submission was crude, but early. My final submission is probably a factor of 10X better, but two hours before the deadline.
So without giving too much away YC, which iteration gets reviewed and when, and how do you know when the submission is final, if you review before the close date?
