The engagement dropped by 15% this week. Walk through your investigation process.
This product question from Grubhub's Phone Screen goes beyond feature brainstorming. The interviewer expects a framework-driven approach that considers market dynamics, user segmentation, and data-informed decision making.
What the Interviewer Expects
- Identify the target user and their core problem
- Propose reasonable solutions with basic prioritization
- Define 2-3 key success metrics
- Consider basic trade-offs and risks
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
- How would you sequence the rollout across different user segments?
- How would you validate this idea before committing engineering resources?
- How would you handle pushback from engineering on feasibility?
- How would you decide to kill this feature if it's not working?
