What this question tests
Tests problem diagnosis before solutioning: identifying the actual worst moments in a service marketplace booking flow.
How to approach it
- Identify likely worst moments: last-minute cancellation, no taskers available, or a price surprise at booking.
- Pick the highest-impact one, like last-minute cancellations, which leave customers stranded with no time to rebook.
- Diagnose why it happens: taskers overcommit across jobs with no penalty, confirm with the interviewer.
- Design the solution: instant backup-tasker auto-matching on cancellation, plus a reliability score affecting ranking.
- Prioritize the auto-rematch flow first, since it directly addresses the customer being stranded.
- Define success as reduced bookings with zero fulfillment and faster time-to-rebook after cancellation.
What a strong answer includes
- Picks one specific worst-experience scenario and explains why it's the worst, not a shallow list.
- Proposes a fix addressing the root cause, tasker overcommitment, via incentives, not just a UI patch.
- Chooses a success metric tied directly to the pain point, not vague satisfaction.
Common mistakes
- Listing many bad experiences without picking one to solve deeply.
- Proposing a fix that doesn't address why the cancellation happened in the first place.
Likely follow-up questions
- How would you penalize taskers who cancel repeatedly without hurting good taskers?
- How would you handle categories with few available taskers?
- What would you measure to know trust improved?
