Give concrete examples: detailed PR descriptions, decision logs in shared docs, or recorded walkthroughs. Show that your communication works even when no one is online at the same time.
Strong answers include: writing clear, self-contained messages (not "hey, got a minute?"), documenting decisions in shared spaces, using async communication by default and synchronous calls intentionally, recording meetings for absent team members, and being explicit about availability and response expectations.
Essential modern skill. Candidates who rely entirely on real-time communication will struggle in distributed teams. Look for writing quality and intentional communication habits.
