Three of the questions

  1. Walk me through how you'd define SLOs and SLIs for a platform like your internal observability tool itself - not for an application team, but for the platform that ingests metrics, logs, and traces. What would you measure, and what would you consider acceptable error budget consumption?
    Technical depth · from the posting: “Contribute to service readiness through dashboards, SLOs, SLIs, runbooks, resilience checks, and performance validation.”
  2. It's 2am and your observability platform's own alerting pipeline goes down - so teams relying on it for monitoring their services are now blind. Walk me through how you'd triage this, given this is the platform itself failing, not a downstream app.
    Scenarios & troubleshooting · from the posting: “We use it to help engineering and service teams detect issues earlier, reduce incident impact, and improve operational reliability”
  3. Tell me about a time you had to write or maintain operational documentation—a runbook, support guide, or onboarding material—and how you knew it was actually useful to your team.
    Behavioural · from the posting: “Experience writing or maintaining operational documentation such as runbooks, support guides, or onboarding material.”
