What metrics would you use to measure the success of push notifications? How would you set up tracking?

This product question from Postmates's Take-home Project 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
  • 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
User segmentation and personas
Product strategy and vision
Go-to-market strategy
Success metrics and KPIs
How to Approach This
  1. Start with the user. Who are they, what problem do they have, and what is their current workaround?
  2. Use a prioritization framework: impact vs effort, RICE scoring, or ICE scoring.
  3. Define success metrics using the AARRR framework: Acquisition, Activation, Retention, Revenue, Referral.
  4. 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 decide to kill this feature if it's not working?
