What this question tests
Product design extending a ride-hail platform into delivery, using existing driver supply as the core asset.
How to approach it
- Clarify the delivery type: food, groceries, or packages, since each has different demand patterns and competitive landscape.
- Segment the opportunity: use idle driver time between rides in off-peak hours to serve delivery demand, an asset-utilization angle unique to Lyft's supply.
- Identify the pain point: Lyft's driver utilization dips off-peak, while delivery demand often peaks at complementary times.
- Prioritize package and grocery delivery over food, since DoorDash and Uber Eats already dominate restaurant delivery.
- Design the solution: a delivery mode drivers can toggle into during ride lulls, matched to nearby requests using the existing app and rating system.
- Define success: incremental driver earnings during off-peak hours and delivery fulfillment time versus dedicated delivery competitors.
What a strong answer includes
- Grounds the strategy in Lyft's real asset, underutilized driver time, rather than just copying Uber Eats.
- Picks package and grocery delivery specifically because it avoids head-on competition where Lyft has no edge.
- Proposes a concrete mechanism, toggle into delivery mode during lulls, that reuses existing infrastructure.
- Uses driver earnings lift as a success metric, tying the feature to Lyft's actual supply-side retention problem.
Common mistakes
- Proposing to directly compete with Uber Eats and DoorDash in restaurant delivery without acknowledging the disadvantage.
- Ignoring Lyft's actual asset, idle driver time, as the strategic rationale.
- Not defining a success metric tied to driver economics.
Likely follow-up questions
- How would you handle drivers who prefer only rides, not deliveries?
- How would you price delivery to be competitive without undercutting driver earnings?
- How would this affect ride availability during high-demand hours if drivers shift to delivery?
