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.

Chipotle CBO Chris Brandt filters candidates based on a simple, visceral question: 'Would you be willing to walk into a conference room with them at 5 PM on a Friday?' This test prioritizes collaborative spirit and cultural fit over pure skill, ensuring new hires won't disrupt team dynamics, even if they look good on paper.

Create a public document detailing your company's operating principles—from Slack usage to coding standards. This "operating system" makes cultural norms explicit, prevents recurring debates, and allows potential hires to self-select based on alignment, saving time and reducing friction as you scale.

Before writing a job description, create an in-depth scorecard with three components: the role's Mission (its purpose), key Outcomes (measurable results), and Competencies (functional and cultural skills). This forces alignment among stakeholders and clarifies what success looks like before the first interview.

To build a culture of continuous improvement, prioritize hiring for coachability. Individuals with backgrounds in competitive athletics or music are often ideal because they have been heavily coached their whole lives. They view direct feedback not as criticism, but as an essential tool for getting better.

To scale from 100 to 1,000+ employees, you must stop interviewing everyone. Success depends entirely on the cultural foundation built with the first 100 people. By personally hiring and imbuing them with the company's core values, you create a group of leaders who can replicate that culture as the organization expands.

For roles where you hire for personality and train skills from scratch (like HVAC techs), traditional recruiting is inefficient. Use local ads to generate high volume and group interviews to quickly triage candidates and identify the right cultural fit before moving to one-on-ones.

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.
