I never knew how hard people prepared for the interview. Great resource for that. The headline is a bit misleading though because it implies they aren't in YC

I never knew how hard people prepared for the interview. Great resource for that. The headline is a bit misleading though because it implies they aren't in YC now. If not for the the interview-prep part the entire story could be TL;DR-ed into "We got into YC, someone accidentally sent a scary email"
