Difficulty: medium
Interview Round: Other
Explain the difference between horizontal integration and vertical integration as growth strategies. Define each, support the definitions with real examples, and describe when a company would choose one over the other and what each costs.
```hint Picture the chain
Sketch the stages a product passes through on its way from raw inputs to the end customer. For any expansion, ask where it lands relative to the stage the company already occupies.

### Clarifying Questions
- Do you mean integration as a corporate strategy along a value chain, or the related software usage in which a horizontal product serves many industries and a vertical product serves one?
- Should vertical integration be covered in both directions, toward suppliers and toward customers?
- Do moves a company makes by building in-house count, or only mergers and acquisitions?
- Would you like examples from technology companies specifically, or from any industry?
### What a Strong Answer Covers
- Precise definitions of both strategies anchored on the value chain, including backward and forward vertical integration.
- Real examples that are classified correctly, ideally including technology companies.
- The motives behind each strategy and the conditions under which each pays off.
- The costs and risks of each, such as competition-law scrutiny, integration difficulty and loss of flexibility.
- How the distinction informs product decisions such as whether to build, buy or partner.
### Follow-up Questions
- A large social platform buys a fast-growing photo-sharing app. How would you classify the deal, and what would a competition regulator examine?
- An app company depends on other firms' phones and app stores to reach its users. When would building its own hardware be worth it, and when would partnering be the better choice?
- Can one company pursue both strategies at the same time? Give an example and the main risk of doing so.

It tests precise value-chain definitions, correctly classified real-world examples, the motives and risks behind each strategy, and how the distinction shapes build, buy or partner decisions.
