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.

During a reference check, instead of asking about weaknesses, a young Jeff Bezos asked: "Give me an example of a job that she wouldn't be a good fit for." This clever reframing bypasses generic praise and forces the reference to provide specific, nuanced feedback on a candidate's limitations.

Standard reference checks yield generic praise. To identify true A-players, ask their former colleagues a high-stakes question: “Would you quit your current job to work for this person again?” An enthusiastic “yes” is the strongest hiring signal you can get.

For hiring, Scott Galloway advocates for prioritizing "reference hiring" above all else. He trusts a strong recommendation from a credible source so much that he considers the candidate an "80, 90% lock on the job" before they even interview. This suggests vetted referrals are a far more reliable signal of quality than traditional interview performance.

Artemis moves reference checks to the beginning of their hiring process, not the end. They've found an almost perfect correlation between the strength of references and on-the-job performance. This allows them to de-risk candidates and make high-conviction offers within just one or two days.

Standard reference calls are predictably positive. To get the truth, ask the reference, "What job do we need to hire next to help this person be successful?" The description of the required role will almost always be a perfect antonym of the candidate's skills, revealing their weaknesses.

When hiring for corp dev roles, assess abstract qualities like work ethic and resilience by asking candidates specific probing questions. Then, ask their provided references the exact same questions to see if the stories corroborate and gain a true sense of character.

Interviews are often misleading. A trusted recommendation from a high-performing employee or contact is a more reliable signal of a candidate's quality than your own interview assessment. This "reference hiring" is a secret weapon for building a strong team.

Zipline considers candidate-provided references to be useless ("paid references"). Instead, they invest significant time to network their way to former colleagues not on the official list. These blind references provide brutally honest feedback, revealing both A+ players and those who "leave a trail of destruction."
