Prioritizing a candidate's skills ('capacity') over their fit with the team ('chemistry') is a mistake. To scale culture successfully, focus on hiring people who will get along with their colleagues. The ability to collaborate and integrate is more critical for long-term success than a perfect resume.

To avoid the trap of hiring 'good enough' people, make the interview panel explicitly state which current employee the candidate surpasses. This forces a concrete comparison and ensures every new hire actively raises the company's overall talent level, preventing a slow, imperceptible decline in quality.

To hire for traits over background, Mark Kosaglo suggests testing for coachability directly. Run a skill-based roleplay (e.g., discovery), provide specific feedback, and then run the exact same roleplay again. The key is to see if the candidate can actually implement the coaching, not just if they are open to receiving it.

In a rapidly changing environment, adaptability ('malleability') is key. To get past rehearsed answers about work projects, ask candidates to describe personal changes they've made in their own lives. This reveals their genuine capacity for self-reflection and adaptation.

A common hiring mistake is prioritizing a conversational 'vibe check' over assessing actual skills. A much better approach is to give candidates a project that simulates the job's core responsibilities, providing a direct and clean signal of their capabilities.

When interviewing, ask candidates: 'In six months, what would be a nightmare situation for you here?' Their answer reveals their work-style preferences and anxieties, highlighting potential mismatches with your company's reality and helping you hire for retention.

The chaotic, underdog nature of a startup is a binary filter. Frame this reality honestly during interviews. The right candidate will be energized by the challenge, while the wrong fit will be stressed. This question quickly reveals cultural suitability.

Instead of generic interview questions, ask what truly motivates a candidate and what they'd do for a hobby if money weren't an issue. The way they describe these passions reveals their energy, personality, and core drivers far more effectively than rehearsed answers about work experience.

Rather than using personality assessments to accept or reject candidates, the firm uses the results to craft more insightful interview questions. This helps them probe for specific traits and understand role fit without making the test a pass/fail gate, acknowledging there is no single 'good' personality.
