The activation rate dropped by 15% this week. Walk through your investigation process.
Visa asks this during the Take-home Project 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
- 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
- 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?
- What competitive response would you expect and how would you prepare?
