imo it's probably better to be rejected at this stage than the interview stage.
I previously got an interview and spent 4 days in travel (they only fund the cheapest flights on hipmunk, which often has several connections), for a 10 minute interview where I thought most of the questions were answered in my written application, only to be rejected anyways.
I'm sure there are sound reasons for the short interview time, but it feels disproportionate to the effort. The best part of that experience was probably talking to the other startups.
