How do you work with engineers as a product manager? Describe your approach and support it with a specific example.
```hint Show it under strain
Collaboration is easy to describe when everyone agrees. Choose an example where you and the engineers disagreed about scope, a deadline or technical debt, and show how the decision got made.

### Clarifying Questions
- Would you like my general operating model, one specific story, or both?
- Should the example center on day-to-day delivery, or on a disagreement such as scope versus a date, or new features versus technical debt?
- What team setup should I assume: a small team where engineers talk to users directly, or a larger one with dedicated designers and engineering managers?
### What a Strong Answer Covers
- How engineers take part in problem definition and discovery instead of receiving finished specifications.
- A clear split of decision rights: the PM owns the problem, priority and success measure, engineering owns how it is built and the estimates, and trade-offs are made together.
- How scope, deadlines, technical debt and reliability work are negotiated, shown through a concrete disagreement and its resolution.
- Habits that keep context shared, such as written problem briefs, decision logs and quality bars agreed in advance.
- What the candidate learned and changed after something went wrong.
### Follow-up Questions
- Tell me about a time an engineer said your plan would not work. What did you do next?
- How do you decide how much of the roadmap goes to technical debt and reliability?
- Engineering estimates twice as long as leadership expects. How do you handle it?
