Your team is considering building a social feed. How would you evaluate this decision?
Cruise asks this during the Technical Screen to assess your product sense and structured thinking. They want to see how you define the problem, identify the target user, prioritize features, and measure success.
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
- What competitive response would you expect and how would you prepare?
- How would you sequence the rollout across different user segments?
- How would you handle pushback from engineering on feasibility?
