Plan the launch of multiple emotion reactions on Facebook when only Like exists
Company: Bolt
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager at Facebook at a time when the only way to respond to a post with one tap is the Like (thumbs-up) button. The company has already decided to offer several reactions instead of just one. How would you take this from decision to launch?
Explain the goal you would set, the product decisions you would need to settle, how you would build, test and roll the feature out, and how you would judge whether it worked.
```hint Two sides of every reaction
Every reaction involves the person reacting and the person whose post receives it. Keep both in mind when you design the experience, and especially when you plan the test, since those two people may not be in the same experiment group.
```
### Clarifying Questions
- Has the set of new reactions already been chosen, or is deciding which emotions to offer part of my job?
- Is the first release limited to posts, or does it also cover comments, Pages and Groups?
- What does leadership most want from the change: more fitting feedback on posts where Like feels wrong, such as sad news, more engagement overall, or a richer signal for News Feed ranking?
- Should iOS, Android and desktop web, and every country, launch together, or am I free to stage the rollout?
### What a Strong Answer Covers
- A clear launch goal tied to the feelings a lone Like cannot express, stated as a testable hypothesis
- The product decisions to settle before building: which reactions, how people pick one on mobile and desktop, how reactions appear in counts and notifications, and how they feed News Feed ranking
- A build, test and staged rollout plan, including a test design that copes with reactors and posters landing in different groups
- Success metrics for both reactors and posters, plus guardrails such as comments, shares and accidental reactions
- Launch risks: misuse of negative reactions, emoji meaning across cultures, accessibility, and compatibility with ad reporting and developer integrations
### Follow-up Questions
- After launch, reactions per user rise but comments per user fall. Do you call the launch a success?
- How much should each reaction count in News Feed ranking compared with a Like, and how would you find out?
- Weeks after launch, the angry reaction is used heavily on news and public-figure posts. Would you change anything?
Overview: A product manager interview prompt about launching multiple emotion reactions on Facebook at a time when people could only Like a post. It tests launch planning: setting a goal, settling the key product decisions, designing a rollout and a test that copes with social network effects, and choosing success metrics and guardrails.
