The engagement dropped by 15% this week. Walk through your investigation process.
Instacart 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
- Demonstrate strategic product thinking beyond feature-level decisions
- Analyze second-order effects and long-term ecosystem impact
- Balance multiple stakeholder needs with clear trade-off rationale
- Design experiments to validate key assumptions before building
- Consider platform effects, network effects, and marketplace dynamics
- Propose a phased rollout strategy with go/no-go criteria
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 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?
