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.

Prioritize hiring generalist "athletes"—people who are intelligent, driven, and coachable—over candidates with deep domain expertise. Core traits like Persistence, Heart, and Desire (a "PhD") cannot be taught, but a smart athlete can always learn the product.

For channel roles, prioritize candidates who are coachable and curious. These traits indicate a high growth mindset and predict long-term success more reliably than a pre-existing network of relationships, which can be built over time through credibility and a structured process.

When hiring, a candidate with high passion for the subject matter but low experience is more valuable than an experienced candidate with low passion. Skills are teachable, but genuine enthusiasm for the mission is not. This framework helps resolve the common hiring dilemma between potential and polish.

To accurately assess an unteachable trait like coachability, you can't just ask about it. You must create a situation that requires it. For coachability, run a brief role-play, provide direct feedback, and ask them to do it again, observing their verbal and non-verbal reactions to the coaching itself.

Alpine's hiring philosophy for leaders downplays resume experience, instead focusing on core attributes like grit, humility, and emotional intelligence. They believe these traits are better predictors of success and that specific business skills can be trained on top of this strong foundation.

Sales experience on a resume can be a 'false positive.' When hiring SDRs, prioritize untrainable qualities like work ethic, mindset, and resilience over specific past roles. These character traits are a better predictor of long-term success than skills that can be taught.

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.

The "attitude vs. aptitude" debate is flawed. Instead, hire the person with the smallest skill deficiency relative to the role's requirements. For a cashier, attitude is the harder skill to train. For an AI researcher, technical aptitude is. The key question is always: is it worth our resources to train this specific gap?
