OK so all of you who submitted the application on-time have received your response email. Does anyone know when I should expect a response if I applied late? Will I even get a response?
We haven't heard yet and were a late applicant too.
Not sure if we'll get a reply in time to make it over to the states (from Australia), but the FAQ suggests that they will respond at some point:
"You can submit a late application up till the start of the summer 2012 YC cycle in June, but we can promise nothing about how carefully we'll read it or when we'll respond to you."
