How to Pass the Persimmon Product Manager Interview in 2026
The Persimmon DNA (TL;DR)
The "New Build Boost" principle at Persimmon drives the evaluation of how candidates approach market opportunities, specifically assessing their capacity to identify and articulate value propositions for customers using tools like "Deposit Boost" or "Part Exchange".

The Danger Zone: Top Reasons Candidates Fail
Based on our database of Persimmon interview outcomes, avoid these common traps:
- Not involving relevant stakeholders (e.g., engineering, QA) in the investigation process.
- Designing a feature-rich product without considering feasibility, cost, or integration with existing systems.
- Focusing solely on feature comparison without considering business model, pricing, or target audience.
- Focusing on what others did rather than their own actions and contributions.
