You’re a CTO so I imagine you’re hiring mostly directors and VPs and it comes down to whether you like the candidate or not. At a lot of companies you just have to be noticeably better than everyone else because after 5+ employees interviewing 5+ candidates, most managers have had enough with the time the team has sunk into that process. As a candidate, if you can find out how long the role has been open, you can really play ball.
