← Google Cloud (GCP) Interview Insights
My first instinct was to jump straight into features, audio cues, braille buttons, haptic feedback, and I kind of just listed things without grounding it in actual user needs first.
Start by clarifying the scope and constraints, then frame the problem around the user journey and accessibility needs. Structure your answer by defining user personas, mapping the end-to-end experience, and proposing solutions that leverage both physical and digital touchpoints. Emphasize inclusivity, safety, and independence while tying back to Google Cloud's strengths in AI and voice.
Pro tip: Show empathy by considering the full spectrum of visual impairments, including those with partial sight, and avoid assuming all blind users have the same needs. Also, mention the importance of testing with actual blind users and adhering to accessibility standards like WCAG.
Ask clarifying questions to understand the context: Is this for a new building or retrofitting existing elevators? What is the budget and timeline? Are there other disabilities to consider? This shows structured thinking.
Identify primary users (blind individuals) and secondary users (e.g., those with low vision, elderly). Outline their key needs: independence, safety, efficiency, and ease of use.
Break down the elevator experience into stages: approaching the elevator, calling it, entering, selecting a floor, riding, and exiting. Identify pain points at each stage for blind users.
Propose solutions for each stage, leveraging technology (e.g., voice control, smartphone apps, haptic feedback) and physical design (e.g., tactile buttons, Braille, audio announcements). Prioritize based on impact and feasibility.
Suggest testing with blind users, measuring success metrics (e.g., task completion time, user satisfaction), and iterating. Mention compliance with accessibility standards.
