Product questions at Waymo 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
- 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 decide to kill this feature if it's not working?
- What would you do if usage data contradicts user feedback?
