The engagement dropped by 15% this week. Walk through your investigation process.
Product questions at Vercel test your ability to think like a product leader. This Phone Screen question evaluates how you balance user needs, business goals, and technical constraints when making product decisions.
What the Interviewer Expects
- Apply a structured framework for product thinking (user, problem, solution, metrics)
- Segment users and identify differentiated needs
- Prioritize features using a clear framework (RICE, ICE, impact vs effort)
- Define comprehensive success metrics across the user funnel
- Consider competitive dynamics and market positioning
Key Topics to Cover
How to Approach This
- Start with the user. Who are they, what problem do they have, and what is their current workaround?
- Use a prioritization framework: impact vs effort, RICE scoring, or ICE scoring.
- Define success metrics using the AARRR framework: Acquisition, Activation, Retention, Revenue, Referral.
- Consider second-order effects. A feature might boost short-term engagement but hurt long-term retention.
Possible Follow-up Questions
- What would you do if usage data contradicts user feedback?
- How would you sequence the rollout across different user segments?
- How would you decide to kill this feature if it's not working?
- How would you handle pushback from engineering on feasibility?
