Structure a spoken PM product-sense answer with assumptions, segmentation, pain-point prioritization, and MVP tradeoffs. Use when practicing design, improve, or build-next interview questions.
argument-hint
[interview prompt]
intent
Coach PM candidates through open-ended product-sense interviews using a repeatable six-part answer spine: clarify, rationale, goal, segmentation, pain points, and solution choice. Use this to practice product design and product improvement questions, avoid solution-first answers, and produce responses that sound thoughtful out loud rather than over-scripted on the page.

Purpose
Help PM candidates and interview coaches structure product-sense answers that sound strong out loud, not just on paper. Use this when practicing prompts like "How would you improve X?", "Design a product for Y", or "What would you build next for Z?"
This is not a memorize-and-recite script. It is a reasoning scaffold that prevents solution-jumping, forces real prioritization, and leaves the interviewer with a clean story they can follow.
Input
Works best with: The interview prompt you're practicing (e.g., 'How would you improve X?', 'Design a product for Y').
Also useful: The company/role you're interviewing for and how much time the answer gets.
Anything supplied with the invocation itself — text after the skill name, a pasted context dump, or an appended ARGUMENTS: line — counts as answers already given. Use it and skip whatever it covers; don't re-ask.
Arriving empty-handed? That works too. The skill asks for the prompt, then walks the reasoning scaffold with you out loud.
Example invocation:Practice this: 'How would you improve Google Maps for commuters?' — 25-minute answer, L5 PM loop.
Key Concepts
What Product Sense Interviews Actually Test
Strong product-sense answers do more than generate ideas. Interviewers are usually testing whether you can:
Segment thoughtfully instead of talking about "everyone"
Prioritize one pain point instead of describing ten equally
Make tradeoffs explicit when choosing an MVP
Communicate clearly under time pressure
The Six-Part Answer Spine
Clarify - Reduce ambiguity, define scope, and state assumptions.
Rationale - Explain why the problem matters now for the market and, if relevant, the company.
Product Goal - Define the user outcome you want to create before talking about features.
Segmentation - Choose who to serve first and show why that target wins.
Pain Points - Map the journey, name the main frictions, and pick the one worth solving first.
Solution - Generate distinct options, compare them, and commit to one MVP with clear exclusions.
The order matters. If you skip from prompt to feature ideas, your answer sounds clever but ungrounded. If you establish the user, goal, and pain first, your solution feels earned.
Why This Works
Prevents feature dumping: You do not start with ideas before you know whose problem you are solving.
Balances user and business thinking: The answer includes demand, company fit, and strategic tradeoffs rather than pure UX talk.
Creates a speakable narrative: Each section becomes a short checkpoint the interviewer can follow.
Forces prioritization: Reach, impact, fit, frequency, severity, and effort all surface tradeoffs instead of hand-wavy optimism.
Anti-Patterns (What This Is NOT)
Not a feature brainstorm: Listing ideas without choosing a target user or problem is not product sense.
Not a TAM presentation: You do not need made-up market numbers to sound strategic.
Not a memorized monologue: Rigid scripts break as soon as the interviewer redirects or narrows scope.
Not a business-case-only answer: Product sense still requires empathy, behavior, and user context.
When to Use This
Product design questions
Product improvement questions
"What would you build next?" prompts
Mock interviews where you want a repeatable spoken structure
When NOT to Use This
Behavioral interviews that need STAR stories
Execution and analytics cases that revolve around metrics diagnosis
Go-to-market or pricing interviews where distribution or monetization is the main problem
Application
Use template.md as the working structure.
Delivery Rules
State your structure early so the interviewer knows where you are going.
Ask only 1-2 clarifying questions. More than that feels like stalling.
Keep lists MECE where possible: segments should be distinct, pain points should not overlap, and solutions should not be three versions of the same thing.
Speak in short sentences. Interview answers should sound conversational, not like a memo read aloud.
If the prompt does not name a company, use a startup assumption and skip fake company-mission talk.
Step 1: Clarify the Prompt
Start by surfacing the two ambiguities that change the answer most. Good clarifiers usually narrow:
Product or surface area
User group
Time horizon
Business model or operating constraints
If the interviewer does not answer, state your assumptions and move on. The goal is to unblock the rest of the answer, not to turn the interview into requirements gathering.
Quality bar: Ask questions that materially change the solution. "Are we talking mobile or desktop?" matters less than "Are we optimizing for viewers, creators, or advertisers?"
Step 2: Build the Rationale Before the Feature
Explain why the space matters now.
For the market view, cover:
Why the market is big or strategically important
Why the problem matters to real people
Why now is a good moment to act
If a company is named, then add:
Mission fit
Business objective
Competitive landscape
Market gap
Unique strength
End this section with a one-line thesis. That thesis should make the rest of the answer feel inevitable.
Quality bar: Use qualitative signals unless you know the numbers cold. Fake precision is worse than grounded judgment.
Step 3: Define the Product Goal
Write one sentence in this format:
Help [user] [achieve outcome], so that [broader impact].
Then describe what success looks like for the user in observable terms.
Good: "Help beginner YouTube learners find content they are glad they watched, so that the platform becomes an intentional learning destination."
Bad: "Build a personalized AI learning path feature." That is a solution disguised as a goal.
Step 4: Segment the Market and Pick a Target
Do not jump straight to persona. First identify the ecosystem players, then choose the player you want to serve. After that, choose two segmentation dimensions that actually change needs.
Good segmentation dimensions usually change:
Goal or job to be done
Stakes or consequence level
Expertise level
Workflow constraints
Frequency of the problem
Weak dimensions are often demographic cuts that do not change the product meaningfully.
After choosing your target segment:
Give a brief reach / impact / strategic-fit rationale
Write a two-sentence persona
Keep the persona free of pain points; pain comes next
Step 5: Map Pain Points and Prioritize One
Break the user journey into 4-6 stages. Then list the frictions across that journey.
Prioritize the top pain point using:
Frequency - how often the user hits it
Severity - how badly it blocks the job, how underserved it is, and the emotional cost
This is the fulcrum of the entire answer. If the pain point is vague or weak, the solution section becomes generic.
Quality bar: Pain points should describe user friction, not missing features. "No structured progression after each video" is a pain. "No AI learning path" is already a solution.
Step 6: Generate Options, Choose an MVP, and Close
List three distinct solutions. They should solve the same pain in different ways, not represent three feature line-items inside one idea.
Evaluate each option on:
User impact
Effort
Then choose one MVP and specify:
Core features
1-2 explicit v1 exclusions
Top risks and mitigations
Close with a one-sentence recap that names:
Target segment
Top pain point
First bet
That final sentence is what the interviewer should remember.
Examples
Good Example: Improve YouTube for Beginner Learners
See examples/improve-youtube.md for a full worked example.
What makes it strong:
It chooses one player first: viewers, not "everyone in the ecosystem"
It segments by learning intent and expertise level, which both change needs materially
It picks one pain point: no structured progression across videos
It compares multiple solutions before choosing Learning Paths as the MVP
Good Example: Design a Fire Alarm for the Deaf
A strong answer to this prompt would explicitly state a startup assumption if no company is named, prioritize people who live alone, and choose the wake-up problem before discussing dispatch or smart-home integrations.
What makes this example useful:
The target segment is clear and high-stakes
Severity matters more than broad reach
Hardware, software, and ecosystem constraints are part of the reasoning
Anti-Pattern Example
"I would improve YouTube by adding AI summaries, better recommendations, creator analytics, and a study mode."
Why this fails:
No target user
No prioritized pain point
No business or market logic
Four ideas that were never compared against each other
This kind of answer can sound energetic in the moment, but it signals weak PM judgment.
Common Pitfalls
Solution-first thinking: You start pitching features before naming the user or problem. Fix it by forcing yourself to write the product goal and top pain point before brainstorming solutions.
Segmentation theater: You list many segments, then pick one with no tradeoff logic. Fix it by explicitly comparing reach, impact, and strategic fit.
Goal-as-feature: Your "goal" describes the thing you want to build. Fix it by rewriting it as a user outcome.
Pain points that are really solutions: "Users need a dashboard" is not a pain point. Rewrite in user-language first.
Three fake options: Your three solutions are really one solution with minor variations. Fix it by varying the product mechanism, not just the packaging.
Weak close: You end after listing features. Fix it by restating the target segment, the pain, and the first bet in one sentence.
Over-answering every branch: You try to prove breadth instead of making choices. Product-sense interviews reward focus more than exhaustiveness.
