In PM interviews, you may be asked to design products or features specifically for children, such as:
- Design a mobile app that helps 6–10-year-olds learn math in a fun way.
- Design a wearable gadget for kids to track physical activity and encourage healthy habits.
- Design a YouTube app for kids under 10.
These questions test your product sense, empathy, prioritization, and ability to think about multiple stakeholders. Here’s a detailed guide to answering them effectively.
1️⃣ Clarify the Age Group and Product Goal
Why it matters: Kids’ abilities and interests change a lot depending on their age. A 6-year-old cannot read complex instructions like a 10-year-old.
Tips:
- Ask or clearly state the age range (e.g., 6–10).
- Define the goal of the product: Is it learning, entertainment, health, or a combination?
- Clarify constraints: device type (mobile, wearable), budget, time, or privacy regulations.
Example:
“Are we designing a math-learning app for children aged 6–10, and should it work on both tablets and smartphones?”
2️⃣ Understand Users and Stakeholders
Why it matters: Kids are the primary users, but they aren’t the decision-makers. Parents often control whether a child can use the product.
Tips:
- Primary users: Children — consider attention span, reading ability, motor skills, and curiosity.
- Secondary users: Parents — they care about safety, screen time, and content quality.
- Tertiary users: Teachers, content creators, or health professionals if applicable.
Example:
- Kids want interactive math games.
- Parents want progress tracking and time limits.
3️⃣ Safety and Trust Are Critical
Why it matters: Parents will not let children use a product they don’t trust. Safety is non-negotiable.
Tips:
- Include parental controls: time limits, approval for activities, dashboards to track usage.
- Ensure content moderation: no inappropriate content.
- Follow privacy regulations, e.g., COPPA or GDPR-K.
Example:
Only allow children to access vetted content, and provide parents with weekly usage reports.
4️⃣ Keep Design Simple and Visual
Why it matters: Children have limited reading ability and shorter attention spans.
Tips:
- Use big, colorful buttons and visual navigation instead of text-heavy menus.
- Keep interactions intuitive so kids can explore independently.
- Avoid unnecessary complexity.
Example:
- A math app could use drag-and-drop number puzzles instead of multiple-choice questions.
5️⃣ Balance Fun and Purpose
Why it matters: Children engage best when learning or healthy habits are gamified or fun.
Tips:
- Include rewards, challenges, or levels to motivate engagement.
- Ensure activities align with the product goal (learning, physical activity, creativity).
- Avoid features that encourage excessive screen time.
Example:
- Wearable gadget: award badges for daily activity goals, but send gentle reminders for breaks.
6️⃣ Consider Dual Stakeholders
Why it matters: Kids want independence, parents want oversight.
Tips:
- Features should serve both audiences.
- Example: Kids can earn points or complete tasks, while parents see progress reports and approve new challenges.
7️⃣ Accessibility and Inclusivity
Why it matters: Not all kids interact the same way with technology.
Tips:
- Add voice instructions, subtitles, adjustable font sizes, tactile feedback, or high-contrast visuals.
- Consider children with visual, hearing, motor, or learning disabilities.
Example:
- Math app could read questions aloud or allow touchscreen tracing for counting exercises.
8️⃣ Prioritize Features and Explain Trade-offs
Why it matters: You can’t build everything at once. Interviewers want to see your product judgment.
Tips:
- Prioritize based on impact and necessity:
- Safety & trust → parental controls, moderation
- Core usability & engagement → intuitive UI, gamification, educational content
- Enhancements → voice search, analytics, reminders
- Be ready to explain why some features come first and why others are “nice-to-have.”
Example:
- A wearable tracker should first ensure safety (no harmful sensors), track steps accurately, and then add reward badges or social features.
9️⃣ Define Success Metrics
Why it matters: Interviewers want to see how you measure product impact.
Metrics could include:
- Safety: number of inappropriate content incidents
- Engagement: daily active users, tasks completed, or minutes used
- Parent satisfaction: NPS or approval ratings
- Learning or health outcomes: scores improved, steps taken, or time spent active
Summary
“When designing products for kids, I focus on safety, usability, and engagement while keeping parents’ trust in mind. I prioritize safety first, then core features, then enhancements, and measure success with clear metrics like engagement and outcomes. This ensures the product is fun, safe, and valuable for both kids and parents.”
By following this structured approach, you can confidently answer any PM interview question about designing products for children, demonstrating empathy, strategic thinking, and strong product sense.
