At one startup I did a couple rounds of phone interviews and a full day of in person interviews. Lastly I got to chatting with the co-founder. I can't remember the precise question I asked about how they were building out the team, but I clearly remember the answer. They made the interview process longer and more involved in an effort to narrow the field of candidates. I understand the reasoning: if you think you have a special mission and want people dedicated to that mission, filter by dedication. But I'm not really sure there is a way for any one candidate to consume as much time interviewing for a role as that company could consume out of a pool of candidates. And that includes my smart-ass idea of trying to interview at Pinterest and stopping in the middle of the interview saying "please sign up to see the rest of this whiteboard solution".
