Product positioning teardown: YouTube, TikTok, Instagram and Facebook compared
Company: TikTok
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Explain how Facebook, Instagram, TikTok and YouTube differ from one another as products. Organize your comparison so that the most important contrasts between the four are easy to see.
```hint Choose the axes first
Pick a handful of dimensions, such as why someone opens the app and whose content they end up seeing, and place all four products on each one. Contrasts appear that a product-by-product summary hides.
```
### Clarifying Questions
- Should the comparison center on people who watch and browse, on creators, on advertisers, or on all three?
- Should each product be taken as a whole (Facebook with Groups, Marketplace and Messenger; YouTube with long videos and Shorts) or only its main feed?
- Is there a market or age group to focus on, or should the comparison be global?
### What a Strong Answer Covers
- A small set of comparison dimensions chosen for a reason and applied consistently to all four products.
- The core user need and the mode of use each product serves.
- How content is created and distributed on each: whose content you see, and why.
- Business models and how creators earn on each.
- Where the products now overlap, and what still sets each one apart.
### Follow-up Questions
- Instagram and YouTube both added short vertical video feeds. Why hasn't that erased the differences, and what protects TikTok's position?
- Pick the dimension where TikTok is weakest relative to the other three. What would you build to close the gap?
- A teenager uses all four apps every day. What job does each one do for them?
Overview: A product strategy question asking you to compare Facebook, Instagram, TikTok and YouTube as products.
