Summary

Google PM interview, one question about content moderation on a social platform. Pretty open-ended and I spent more time than I'd like to admit just trying to scope it down.

Questions Asked (1)

How would you prevent harmful or inappropriate content from being uploaded to a social media platform?

Author's notes

My first instinct was to jump straight to ML classifiers and I had to stop myself because that's just the engineering answer, not the PM answer.

Suggested Approach

Start by framing the problem in terms of user harm and platform integrity, then propose a layered defense system combining proactive detection, reactive moderation, and user empowerment. Emphasize trade-offs between scalability, accuracy, and user experience, and suggest metrics to measure success.

Pro tip: Show that you understand the adversarial nature of content moderation: bad actors constantly evolve, so your solution must include continuous learning and adaptation. Also, mention the importance of transparency and appeals to maintain user trust.

1. Define Harm and Scope

Clarify what constitutes harmful or inappropriate content (e.g., violence, hate speech, misinformation) and the platform's policies. Consider legal, cultural, and community standards.

2. Prevention at Upload

Implement proactive measures such as AI-based classifiers, hash matching, and user reporting to flag content before it goes live. Use a combination of automated and human review for edge cases.

3. Detection and Moderation

Deploy real-time detection systems and a moderation pipeline that includes automated tools and human moderators. Prioritize high-risk content and ensure quick response times.

4. User Empowerment and Appeals

Give users tools to report content, control their experience (e.g., filters), and appeal moderation decisions. This fosters trust and distributes moderation effort.

5. Measure, Iterate, and Adapt

Define metrics (e.g., prevalence of harmful content, time to removal, appeal overturn rate) and continuously improve models and policies based on data and feedback.

Key Points to Mention

Layered approach: combine automated detection (AI/ML), human review, and community reporting.
Trade-offs: balance false positives (over-censorship) vs. false negatives (harmful content), and scalability vs. accuracy.
Use of technology: machine learning classifiers, hash matching (e.g., PhotoDNA), natural language processing, and image recognition.
Human-in-the-loop: escalate ambiguous cases to human moderators, and provide support for moderator well-being.
Transparency and appeals: clear community guidelines, user appeals process, and regular transparency reports.
Metrics: measure prevalence, time to action, appeal rates, and user trust to evaluate effectiveness.
