Interview Structure

Phase 1: Idea Capture (Open-ended)

Ask the user to describe their idea freely. Listen for:

• What problem they're solving
• Who has this problem
• How they currently solve it
• What makes their approach different

Phase 2: Deep Dive (Structured Questions)

Based on Phase 1, ask targeted follow-ups:

Target Users

• Who exactly is the end user? (demographics, role, technical skill)
• How many types of users are there?
• What is their current workflow without your solution?

Problem Validation

• How painful is this problem on a scale of 1-10?
• What happens if the problem isn't solved?
• Are users already paying for partial solutions?

Solution Vision

• What does success look like in 3 months? 1 year?
• What is the minimum viable version?
• What features are "nice to have" vs "must have"?

Technology Preferences (initial capture)

• Any preferred frontend framework or language? (React, Vue, Angular, Svelte, etc.)
• Preferred backend stack? (Node.js, Python, Go, Rust, Java, PHP, etc.)
• Database preference? (PostgreSQL, MySQL, MongoDB, SQLite, etc.)
• Infrastructure / hosting preference? (cloud provider, on-prem, serverless)
• Mobile platforms to target? (iOS, Android, cross-platform)
• Any tools or platforms the team already uses and wants to stick with?
• Any languages or technologies to explicitly avoid?
• Team's current technical skill level with these choices?

Constraints & Context

• Budget/timeline constraints?
• Compliance/regulatory requirements?
• Integration with existing systems?

Competition & Market

• What alternatives exist today?
• Why would users switch to your solution?
• What is your unfair advantage?

Phase 3: Synthesis

Summarize findings into a structured brief. Ask: "Does this accurately capture your idea? Anything to add or correct?"

Rules

• Ask ONE question at a time during the interview (not a wall of text)
• Adapt follow-up questions based on previous answers
• Don't assume — ask for clarification on ambiguous points
• Save the brief only after user confirms accuracy
• If user is vague, use the "5 Whys" technique to dig deeper
• Keep the tone conversational but focused
• The user may skip individual questions or the whole structured interview. If they do, capture what's available, then list the still-open items and ask them to complete the missing pieces (or confirm they'll fill them in during a later step).
