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.

Treat hiring as a compounding flywheel. A new employee should not only be a great contributor but also make the company more attractive to future A-players, whether through their network, reputation, or interview presence. This focus on recruiting potential ensures talent density increases over time.

Hiring for "cultural fit" can lead to homogenous teams and groupthink. Instead, leaders should seek a "cultural complement"—candidates who align with core values but bring different perspectives and experiences, creating a richer and more innovative team alchemy.

In niche sectors like aerospace engineering, the pool of senior, diverse talent is limited. A pragmatic strategy is to hire the best available senior specialists while intensely focusing diversity efforts on junior roles and internships. This builds a more diverse next generation of leaders from the ground up.

The common practice of hiring for "culture fit" creates homogenous teams that stifle creativity and produce the same results. To innovate, actively recruit people who challenge the status quo and think differently. A "culture mismatch" introduces the friction necessary for breakthrough ideas.

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.

In a fast-moving environment, rigid job descriptions are a hindrance. Instead of hiring for a specific role, recruit versatile "athletes" with high general aptitude. A single great person can fluidly move between delivery, sales, and product leadership, making them far more valuable than a specialist.

Don't default to hiring people who have "done the job before," even at another startup. Unconventional hires from different backgrounds (e.g., archaeologists in customer success) can create unique creativity. The priority should be finding the right fit for your company's specific stage and needs, not just checking an experience box.

By adding resilience as a core hiring criterion, Pinterest naturally attracts diverse candidates from non-traditional backgrounds who have overcome adversity. This focus shifts hiring away from traditional signals of success, increasing diversity and bringing in employees who are better equipped for business challenges.
