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.

Move beyond surface-level discovery questions. Asking 'What do you value most in a partner?' forces prospects to articulate their core needs for a relationship (e.g., responsiveness, consultation). Their answer quickly reveals if there is a fundamental values alignment, a better predictor of success than technical fit.

Injecting humor or pop culture references into interviews is not just for breaking the ice. It serves as a deliberate test for 'culture fit' by gauging a candidate's sense of humor, which strongly correlates with desirable traits like flexibility, curiosity, and friendliness that are difficult to assess directly.

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.

Ditch standard FANG interview questions. Instead, ask candidates to describe a messy but valuable project they shipped. The best candidates will tell an authentic, automatic story with personal anecdotes. Their fluency and detail reveal true experience, whereas hesitation or generic answers expose a lack of depth.

A candidate can claim they want growth, but their resume tells the real story. Scrutinize *why* they moved between specific companies. A move for a bigger salary versus a move to work under a renowned leader reveals their actual priorities far more accurately than their interview answers.

Instead of answering 'What do you do?' with just a job title, create opportunities for serendipity by offering multiple 'hooks'—mentioning a hobby, a side project, or a recent interest. This gives the other person several potential points of connection, dramatically increasing the chances of an unexpected, valuable interaction.

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.

Directly asking about values often yields aspirational answers. A more effective method is to ask someone who they admire. The qualities they praise in others are a reliable indicator of the values they genuinely hold and strive to embody, revealing their character more accurately than a direct question.
