What this question tests
Accessibility-focused product design for a ride-hailing app, requiring end-to-end thinking from booking through the physical pickup.
How to approach it
- Break the journey into stages with distinct problems: booking, locating the correct car at pickup, communicating with the driver, confirming drop-off.
- Design for booking: full screen-reader compatibility and voice-command ride booking, since visual map interaction is a barrier.
- Design for pickup: audio cues, like a distinct sound the car emits or a phone locator beacon, instead of relying on the user spotting the car visually, plus automatic driver notification.
- Design for in-ride confidence: voice narration of route progress and ETA, and a one-tap way to alert support if something feels wrong.
- Define success as completed-ride rate for flagged trips versus the general population, and driver cancellation rate as a fairness guardrail.
What a strong answer includes
- Solves the hardest sub-problem, finding the correct car among several at a curb, not just making the booking screen accessible.
- Names a discrimination guardrail metric, driver cancellation rate on these trips, a real documented issue in ride-hailing.
- Designs end-to-end, booking to drop-off, not just visual accessibility settings.
Common mistakes
- Only addressing screen-reader compatibility on booking and ignoring the physical pickup and vehicle-identification problem.
- Not considering driver-side behavior, cancellations or refusals, a known real-world accessibility issue.
Likely follow-up questions
- How would you handle a driver who cancels once they learn the rider is blind?
- How would you test this with actual blind riders before launch?
