Product design question

Design a smart watch for blind.

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Whether the candidate designs for accessibility from first principles rather than bolting audio onto a visual interface.

Define the user: fully blind versus low vision users have different needs, so pick one primary segment and note the other as a stretch.
Identify core pain points: inaccessible touchscreens, inability to read notifications, and difficulty with spatial orientation outdoors.
Prioritize jobs the watch should do: haptic and audio navigation cues, voice-first interaction, and emergency/location sharing.
Propose a solution built around haptics (distinct vibration patterns for turn-by-turn navigation) and voice input/output as the primary interface, not a visual screen with voiceover bolted on.
Define success as task completion rate for core jobs (safely navigating a route) and daily active use, not just unit sales.

Designs haptic patterns as the primary interaction model, since audio alone competes with a blind user's need to hear ambient sound (traffic, people).
Includes a caregiver or emergency contact feature, since fall detection and location sharing matter more for this segment than for sighted users.
Tests the concept against a concrete scenario, such as a blind commuter navigating an unfamiliar subway station.

Designing a sighted product first and adding voiceover as an afterthought.
Blocking the user's ambient hearing with heavy audio feedback instead of favoring haptics.
