We interviewed in-person for W17 in October and got rejected because we didn't articulate a good plan for growth. - we grew 4,000% since October - launched huge features for both sides of our marketplace - received acquisition interest in < 3 months of being live - most importantly, made something that people are loving and using on a daily basis.
It's a bummer for sure but not the end of the world.
To anyone who got an interview, Figure out your biggest weakness and a plan for how you overcome it. Your interviewers will exploit it.
Here's some notes on our experience going through the interview https://paper.dropbox.com/doc/YC-Interview-Experience-L45KzT...
Good luck all
