Product Design Prompt (Onsite PM Interview)

You are interviewing for a Product Manager role. Choose a consumer app you genuinely admire and propose two new features that would enhance its value.

For each feature, provide:

Target persona
End-to-end user journey
Technical feasibility
- Backend services/components
- Data flows and storage
- Platform constraints (mobile/web, privacy, offline, performance)
Key success metrics (primary, secondary, guardrails)

Be specific and pragmatic, as if you were aligning with engineering, data, and design to ship a v1.
