May 2026

Summary

Meta data science interview with a product sense question focused on accessibility. Single question, fairly open-ended, and I spent way too long on the feature ideas before realizing they probably cared more about the metrics side.

Questions Asked (1)

Q1

A user advocacy group raises concerns about accessibility for people with hearing disabilities. What product improvements would you propose for Facebook Live and Videos, and how would you measure success?

Author's notes

I went straight into feature brainstorming: auto-captions, caption accuracy improvements, visual sound indicators for Live.

Suggested Approach

Start by framing the problem around the user need—real-time and on-demand accessibility for deaf and hard-of-hearing users—then propose concrete, scalable improvements like automatic captions, sign language overlays, and customizable text settings. Finally, define success metrics that balance user engagement, accessibility adoption, and quality (e.g., caption accuracy) to show measurable impact.

Pro tip: Tie every proposed improvement to a measurable metric and mention the trade-offs (e.g., latency vs. accuracy in live captions) to demonstrate engineering pragmatism and product sense.

1. Clarify the problem and user segments

Restate the concern: deaf and hard-of-hearing users lack equal access to live and recorded video content. Identify key sub-segments (e.g., ASL users, lip readers, those who prefer text) to tailor solutions.

2. Propose product improvements

Suggest features like real-time automatic captions with high accuracy, optional sign language interpretation overlays, customizable caption styling (size, color, background), and a searchable transcript for videos.

3. Prioritize based on impact and feasibility

Rank improvements by user impact, technical complexity, and scalability. For example, automatic captions are high impact but require ML investment; sign language overlays may need manual or partner integration.

4. Define success metrics

Choose metrics across adoption (e.g., % of videos with captions enabled), engagement (watch time, completion rate for deaf users), and quality (caption accuracy, user satisfaction scores). Include guardrail metrics like latency.

5. Outline measurement plan and iteration

Describe how to measure via A/B tests, user surveys, and accessibility audits. Emphasize continuous improvement based on feedback and metric trends.

Key Points to Mention

  • Automatic speech recognition (ASR) for real-time captions with high accuracy (e.g., >95% word accuracy).
  • Customizable caption display options (font size, color, background) to suit individual needs.
  • Sign language interpretation overlay or picture-in-picture for ASL users.
  • Searchable and editable transcripts for recorded videos to improve content discoverability.
  • Metrics: caption adoption rate, watch time among deaf/hard-of-hearing users, caption accuracy, and user satisfaction (CSAT).
  • Trade-offs: latency vs. accuracy in live captions, cost of human-in-the-loop for quality, and scalability across languages.
