I'm a behavioural scientist and I work with startups in their first hires, maybe my experience helps: while it is relatively easy to qualify technical capabilities, most interviews fail to qualify the personality traits of the candidates. This means that only after 6 months or so you realise that you hired a Divider while you wanted a Multiplier. That your new CTO has little patience with the rest of the team, and so on.

We work on fixing that, so we implement a process: founders pick some personality traits they find essential for a great hire, we prepare an interview playbook, and they can be certain that the new guy is actually what they are hoping for.

Interviewing for personality (cultural fit) is hard because we (humans) are hardwired to survive so we give answers that we think are in our favour - and not necessarily truthful. Key to our approach is that we use falsifiable questions, meaning that you can't guess what I believe is a right answer.

If this helps any fellow founders here, am happy to lend a hand.
