Multiple case studies in this report feature co-founders who “never agreed on candidates.” In interviews, the disagreement rarely survived contact with the same written artifact.

When each founder remembered a different call, or scored a different take-home version, conflict looked interpersonal. When both scored the same answers in the ATS, κ rose and meetings got shorter.

That is why InterRater-Hire sits in the published matrix. It is not academic ornament. It is a measure of whether your hiring system produces shared reality.

If your debriefs feel like debate club, fix the artifact trail before you hire a coach.
