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.

A referral from a senior, respected employee can make a huge difference for a borderline candidate, often securing them a follow-up interview they wouldn't otherwise get. However, it cannot override a consensus 'no-hire' decision from the hiring committee. The referral's power is in pushing a candidate over the bubble, not bypassing the evaluation process.

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.

An expensive mis-hire came from a friend's referral. The speaker realized that while she trusted her friends, they lacked the deep marketing expertise to properly evaluate the candidate's skills. This highlights the need to critically assess a referrer's own qualifications in the relevant domain, not just rely on the relationship.

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."

Senior executives are, by definition, excellent at interviewing, making the process unreliable for signal. Instead of relying on a polished performance, ask to see the 360-degree performance reviews from their previous company. This provides a more honest, ground-truth assessment of their strengths and weaknesses.
