Inspired by Shackleton's "hazardous journey" ad, frame difficult roles by being brutally honest about the challenges. This messaging acts as a filter, attracting candidates who are motivated by the struggle and the personal growth it promises, rather than deterring them.

To test an entrepreneur's resolve, Lanny Smith's first piece of advice is to abandon their idea. He believes if simple discouragement can stop someone, they lack the resilience for building a company. Only those with "undeniable faith" will proceed, making it a powerful litmus test.

When asked how he recruits talent for a challenging hardware business, the founder of Allen Control Systems stated it's easy because 'We're making the greatest weapon system in American history.' This demonstrates that for deep tech and defense startups, a powerful and ambitious mission can be more effective than conventional recruiting strategies.

To succeed in its proprietary sourcing model where the default answer is often "no," TA Associates specifically hires individuals who have overcome adversity. They believe this trait builds the necessary resilience and motivation to persist through constant rejection without losing drive.

To gauge a founder's drive and potential for greatness, ask if they have ever been in the top 1% of any field, even an esoteric one. This unconventional question serves as a powerful proxy for ambition and the willingness to push through challenges, regardless of their professional background.

Actively recruiting entrepreneurs whose own ventures recently failed brings in smart, driven individuals with high ownership and a hunger to prove themselves. This is invaluable in the early, capital-constrained days when you need a team with a founder's DNA.

Aravind Srinivas intentionally avoids hiring candidates with established track records from large tech companies. He believes people hungry for their first major success are more motivated and better suited for a startup's intensity than those who may be less driven after a previous big win.

Anduril's counterintuitive "Don't Work Here" campaign was a deliberately crafted filter to repel "mercenaries" only chasing equity. By being brutally honest about its demanding, mission-driven culture, the company successfully attracted aligned candidates and paradoxically increased its qualified application volume by 30%.

Beyond IQ and EQ, interview for 'Resilience Quotient' (RQ)—the ability to persevere through setbacks. A key tactic is to ask candidates about their proudest achievement, then follow up with, 'What would you do differently?' to see how they navigated strife and learned from it.
