Can you describe a situation where you had to collaborate with a challenging colleague to achieve a common goal?

Illustrative answer

This is a fictional collaboration example about behavior, not a personality judgment.

I worked with another engineer on an integration. Their component's interface changed several times without a clear notice, and my work kept breaking. I initially described the situation as them being difficult, but I had also relied on an early example that we had never agreed was the final contract.

I asked for a focused conversation about the shared goal: a working integration with a predictable handoff. I showed the specific mismatches and asked what was driving the changes. They explained that their requirements were still evolving and that they did not know which parts I already depended on.

We agreed on a small versioned contract, representative examples and a change process. Proposed breaking changes would identify affected consumers and require a decision before implementation. I updated my tests against the agreed version and made my dependency dates visible. We also identified the technical lead who would resolve a disagreement we could not settle.

The next integration passed the agreed examples, and we caught a later proposed change before it broke the consumer. We still disagreed on some design choices. The improvement came from making expectations and dependencies explicit, including my own assumptions, rather than trying to change a colleague's personality.

Follow-up to practice

What would you do if the agreed process repeatedly failed after this conversation?
