Ask HN: When should we expect a reply for a late YC S15 application?

We sent a late application a couple of weeks ago, I read that YC cannot say when they'll check and reply to late applications but they do it before the beginning of the program.

Is there any of you who applied with a late application in a previous batch that can share how long it took them to reply and when were the interviews?

We are scheduling many appointments with customers for the end of May and it'd be bad to tell YC to reschedule because we have already other appointments (of the same importance)
