The length of an interview can be a powerful diagnostic tool. A good, engaged candidate conversation should naturally last about an hour. If it ends in 15 minutes, the candidate is likely disengaged. If it stretches to two hours, they may lack the self-awareness to be concise. Use time as a simple filter for cultural fit.
To create a truly safe culture, leaders must demonstrate vulnerability first. By proactively sharing personal struggles—like being a recovering alcoholic or having gone through trauma therapy—during the interview process, leaders signal from day one that mental health is a priority and that it's safe for employees to be open about their own challenges.
To ensure 100% team cohesion, implement a full-day working interview where candidates interact with everyone. Afterward, give every single team member a simple thumbs-up or thumbs-down vote. A single "thumbs down" is a veto, which prevents the poison of a bad cultural fit from entering the team and is easier than firing them later.
