How to Answer: Focus on a specific example that highlights your role in identifying the problem, the steps you took to engage with other departments, and the outcome of your collaborative efforts. Emphasize your communication strategy, how you managed different perspectives, and the technical solutions you implemented. Illustrate your capacity to listen, negotiate, and lead a project to a successful resolution.

Example: “I once faced a situation where our customer service team was getting a surge of complaints about call drops and poor call quality. To get to the bottom of the issue, I immediately reached out to both the network engineering and IT departments. We formed a cross-functional team and met twice daily to assess and share updates.

By collaborating closely, we discovered that a recent software update on our servers had inadvertently disrupted the VoIP settings. The network engineers rolled back the update while IT implemented a patch to prevent future disruptions. Throughout the process, I ensured that communication was clear and that everyone understood the urgency of resolving the issue. As a result, we were able to restore service and significantly reduce customer complaints within 48 hours. This experience reinforced the importance of interdepartmental collaboration for swiftly and effectively solving complex problems.”
