How to Answer
These two terms often get confused, but they represent distinct approaches to how software evolves. This question is your opportunity to show not only your technical knowledge but also your ability to explain process clearly and concisely.
Here’s a clean, confident answer that highlights the difference with precision:
What makes this a strong answer?
- 🧠 Shows a clear conceptual distinction
- 🔁 Explains how both models often work together in real-world workflows
- 📚 Uses simple language with practical relevance
Other great details you could include:
- ➕ Incremental: Builds features step-by-step, like adding bricks
- 🔧 Iterative: Refines those bricks: polishing, updating and improving
- ⚙️ Agile frameworks often blend both approaches in sprints
Why this question matters
This question reveals whether you understand core development strategy and how software evolves over time. Recruiters want to see if you can think beyond just code, and into delivery, learning, and optimization.
It helps them assess whether you:
- 🧭 Understand how to balance speed and quality
- 🔁 Know how to evolve a product, not just build it
- 📣 Can explain technical choices clearly to stakeholders
This is about mindset as much as it is about method.
What the Recruiter Is Really Evaluating
This question uncovers your awareness of software lifecycle management, your ability to explain concepts, and your strategic thinking around product evolution.
| What They Ask | What They’re Evaluating |
|---|---|
| “What’s the difference between iterative and incremental development?” | Your understanding of software delivery methods |
| “How do you apply them?” | Your ability to use process intentionally |
| “Why does it matter?” | Your strategic thinking about product development |
They’re silently asking:
- 🧠 Can this person explain technical models clearly?
- ⚙️ Do they understand how software evolves over time?
- 📈 Will they contribute to a delivery process that improves with each cycle?
Bottom line: Show that you don’t just build, you refine, evolve, and think ahead.
