Three of the questions

  1. Walk me through how you'd operate a Kubernetes-based production deployment system that has to support both regular cloud customers and air-gapped, on-prem customers. What changes between the two in terms of upgrades and lifecycle management?
    Technical depth · from the posting: “Own customer deployments across cloud and air-gapped environments, including installation, upgrades, troubleshooting, and lifecycle management”
  2. It's 2 AM and you get paged because an air-gapped customer's Splunk Agent Resilience deployment failed mid-upgrade and now the cluster is in a half-upgraded state with no internet access for you to pull extra diagnostics. Walk me through what you do.
    Scenarios & troubleshooting · from the posting: “debug complex production issues spanning Kubernetes, networking, storage, and application layers”
  3. The postings mention designing and operating infrastructure across 'cloud and air-gapped environments' and 'multi-region scale'. Tell me about a time when you had to support the same system in two very different deployment contexts. What made it hard?
    Behavioural · from the posting: “Own customer deployments across cloud and air-gapped environments, including installation, upgrades, troubleshooting, and lifecycle management. Experience deploying and supporting cloud and air-gapped/on-prem environments”
