Suggested Approach

Acknowledge that as a software engineer, your primary responsibility is to ensure the safety of people and then protect data and services. Structure your answer around a clear incident response framework: safety first, assess and contain, communicate, recover, and learn. Emphasize that you would follow established protocols and escalate to the appropriate teams rather than acting alone.

Pro tip: Show that you understand the importance of not making things worse: avoid actions like pulling the plug on servers without authorization, as that could corrupt data or disrupt failover systems. Instead, focus on executing your role in the incident command structure and supporting the on-call engineers.

1. Ensure Human Safety

Immediately prioritize the safety of all personnel by following evacuation procedures and alerting others. Do not attempt to fight the fire unless trained and authorized.

2. Activate Incident Response

Trigger the fire alarm and notify emergency services and the data center operations team. Escalate to the on-call incident commander and follow the established communication plan.

3. Assess and Contain

If safe and authorized, help assess the situation (e.g., which systems are affected) and support containment efforts, such as shutting down non-critical systems or activating failover, as directed by incident command.

4. Communicate and Coordinate

Provide clear, concise updates to stakeholders and coordinate with other teams to ensure a unified response. Avoid speculation and stick to verified information.

5. Recover and Learn

After the incident, participate in recovery efforts to restore services and conduct a post-mortem to identify root causes and improve future response.

Key Points to Mention

  • Life safety first: evacuate and account for personnel before addressing infrastructure.
  • Follow established incident response protocols and escalation paths; don't improvise.
  • Avoid actions that could worsen the situation (e.g., cutting power without coordination).
  • Communication is critical: keep stakeholders informed and avoid misinformation.
  • Support failover and redundancy mechanisms to maintain service availability.
  • Conduct a post-mortem to learn from the incident and improve resilience.
