Product improvement plan for emoji reactions on Facebook posts
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Facebook lets people respond to a post with Reactions. Besides the standard Like, pressing and holding the Like button (or hovering over it on desktop) opens a small tray of emoji responses: Love, Care, Haha, Wow, Sad and Angry. You are the product manager who owns Reactions. How would you improve the feature?
Explain the goal you would improve toward, which users you would focus on and what gets in their way today, which changes you would build first, and how you would know they worked.
```hint Follow one reaction end to end
Picture a person scrolling past a friend's post, and the friend who wrote it. Where does the viewer fail to find, choose or send the response they actually feel, and what does the friend lose when that happens?
```
### Clarifying Questions
- What is the goal behind the improvement: more people responding at all, responses that better match how people feel, or better feedback for the people who post?
- Should I cover only reactions on posts in the main Facebook app, or also reactions on comments, in Messenger and on live video?
- Mobile, desktop or both? The tray opens with a press-and-hold on phones and a hover on desktop, so the problems differ.
- Is a known issue prompting this, for example evidence that many people only ever use Like, or is the brief open?
### What a Strong Answer Covers
- A clear goal for Reactions tied to people feeling closer to each other, rather than reaction counts for their own sake.
- Segments on both sides, the people who react and the people whose posts receive reactions, with a justified focus.
- Pain points grounded in how reacting works today (finding the tray, picking a fitting reaction, reactions on sensitive posts) and solutions prioritized by impact and effort.
- Success metrics with guardrails for comment cannibalization, authenticity and misuse.
- Risks such as clutter, emoji read differently across cultures and side effects on feed ranking.
### Follow-up Questions
- After your change, reactions per user go up but comments per post go down. Did it succeed?
- Should Facebook ever suggest a reaction, or apply one automatically? Where would you draw the line?
- How would you decide whether to add a new reaction, and how would you test it with an audience this large?
Overview: A product sense exercise asking a PM candidate how to improve Facebook's emoji Reactions on posts. It tests setting a clear goal, choosing a user segment, identifying pain points in how people react today, prioritizing solutions and defining success metrics with guardrails.
