We've funded people we previously rejected at both stages. I don't think we interviewed Drew the first time. I believe we interviewed the PagerDuties 3 times out of the 4 they applied.
I was under the impression that for YC the the idea was less important than the team.
How did the teams change between rejection and acceptance?
Was a different idea enough to consider them in a different light or is the interview process just sufficiently noisy that they were false negatives earlier?
Have you had many groups accepted after being rejected at interview stage?
