Nw Interviewing Techniques

Testing Commitment

Distinguish interest from commitment.

• "Would you be willing to [specific action]?" | "What would you pay for this?"
• "Can you introduce me to someone else with this problem?" | "When can we schedule a follow-up?"

Exploring Implications

Understand impact and urgency.

• "If this were solved, what would change?" | "What would that enable you to do?"
• "What would happen if we didn't solve this?"

Interview Conduct Rules

Do: Ask about past specifics | Open, non-directive questions | Seek commitment not praise | Keep informal | 80% listening | Talk about their life first

Avoid: Future behavior questions | Leading questions | Accepting compliments as validation | Talking >20% | Mentioning idea before understanding problem | Formal settings

Assumption Challenging

Triggers

Challenge when: belief without evidence | prediction about future | negative feedback dismissed | skipping to solution | single data point relied on

Challenge Format

1. "What evidence supports this?" -- specific past examples
2. "What would disprove this?" -- falsification criteria
3. "What's the opposite assumption?" -- explore alternatives
4. "Who would disagree and why?" -- disconfirming perspectives

Tone: curious and supportive, not confrontational -- goal is truth-seeking.
