Company: Google
Role: Product Manager
Category: Analytics & Experimentation
Difficulty: medium
Interview Round: Other
You are the product manager responsible for Google Doodles, the special artwork and interactive versions of the Google logo that replace the standard logo on the search homepage on certain days. Name the three metrics you would treat as most important for this product, and explain why each one earns its place.
```hint Define success first
Ask what a Doodle is supposed to do for a person who came to Google to search, and what it does for Google, before choosing anything to count.
```
### Clarifying Questions
- Should Doodles be judged as a brand and delight product, or are they also expected to drive search activity, such as searches about the featured topic?
- Do the metrics need to work for both static artwork and interactive Doodles such as games, which invite very different kinds of engagement?
- Are we comparing individual Doodles against each other, or judging the Doodle program as a whole against showing the plain logo?
- Should a worldwide Doodle and one shown in a single country be held to the same scale?
### What a Strong Answer Covers
- A stated goal for Doodles, for users and for Google, that the chosen metrics follow from
- The user journey on a Doodle day (notice, hover, click, learn or play, share) and which step each metric captures
- Exactly three prioritized metrics with clear definitions and reasons for choosing them over close alternatives
- How to attribute an effect to the Doodle itself rather than to the holiday or event it marks
- Guardrails that protect the core search task and the brand
### Follow-up Questions
- A Doodle sets a record for clicks but also draws a wave of complaints about its subject. How do your metrics show that, and what changes next time?
- How would you fairly compare an interactive game Doodle with a static illustration?
- Leadership asks whether Doodles are worth the artists' time at all. What analysis would you run to answer?
