Example: “I make sure to set up regular, concise check-ins with my team and key stakeholders from other departments to align on goals and progress. This can be in the form of brief weekly meetings or written updates, depending on the complexity of the project. I also implement collaborative tools like Slack or Trello to maintain open lines of communication and ensure everyone has access to the same information in real-time.

When I was working on a cross-functional project, I noticed there were misunderstandings about timelines and deliverables between engineering and marketing. I introduced a shared digital calendar and a bi-weekly sync meeting where representatives from each department could voice concerns and updates. This structure streamlined our workflow and reduced miscommunications, leading to a more cohesive team effort and a successful product launch.”
