Summary

Google PM interview question about tracking metrics for a Pixel camera feature that pushes photos to Google Photos. Pretty focused, just the one question from what I can tell, but it's the kind of thing that spirals fast if you don't have a structure ready.

I'd probably start with adoption and then work outward.

Suggested Approach

Start by clarifying the feature's goal and the user journey, then structure your metrics around a framework like HEART or AARRR. Focus on metrics that measure adoption, engagement, and success of the upload flow, and tie them to broader business objectives like Google Photos usage and retention.

Pro tip: Differentiate between leading and lagging indicators, and consider counter-metrics to ensure you're not optimizing for the wrong behavior (e.g., uploads that lead to poor organization).

1. Clarify goals and scope

Ask clarifying questions to understand the feature's purpose, target users, and how it fits into the Google Photos ecosystem. Define what success looks like for this feature.

2. Map the user journey

Outline the key stages: discovering the feature, initiating upload, completing upload, and post-upload actions (e.g., viewing, sharing). Identify potential drop-off points.

3. Select a metrics framework

Choose a framework like HEART (Happiness, Engagement, Adoption, Retention, Task Success) or AARRR (Acquisition, Activation, Retention, Referral, Revenue) to organize metrics.

4. Define specific metrics

For each stage, list quantifiable metrics (e.g., adoption rate, upload success rate, time to upload, retention of uploaders) and prioritize them by importance.

5. Consider trade-offs and counter-metrics

Identify potential negative side effects (e.g., increased storage costs, privacy concerns) and propose counter-metrics to monitor them.

Key Points to Mention

Adoption metrics: percentage of users who use the upload feature, activation rate
Engagement metrics: frequency of uploads per user, number of photos uploaded per session
Task success metrics: upload success rate, time to complete upload, error rates
Retention metrics: retention of users who upload vs. those who don't, impact on Google Photos retention
Counter-metrics: storage cost per user, privacy incidents, user complaints
Business impact: effect on Google Photos monthly active users, cross-product usage (e.g., sharing to other apps)
