"Tell me about a time you had to keep a broad set of stakeholders informed on an important engineering effort without overwhelming them with too much detail. What was the situation, how did you decide what each audience needed, and what was the outcome? If relevant, you can reference how you used tools like Workplace, Messenger, or internal status docs to manage communication."
This question tests whether you can communicate with judgment, not just frequency. For an Engineering Manager at Meta, stakeholders often span engineering, product, design, data science, infra, and leadership, and each group needs a different level of detail to make decisions or stay aligned. Interviewers want to see whether you can create clarity during execution, reduce noise, surface risks early, and tailor communication to the audience.
They are also looking for signs of ownership: did you proactively build a communication mechanism, or did you wait until people asked for updates? Strong candidates show that they understand the tradeoff between transparency and signal quality.
A strong answer uses one concrete example with real stakeholders, clear stakes, and a deliberate communication strategy by audience. The best responses explain what information was shared, what was intentionally omitted, how the candidate adapted when stakeholders needed more or less detail, and what measurable result that communication approach enabled.
