Three of the questions

  1. Walk me through how you'd design a data pipeline in Apache Spark that needs to run identically on-prem on Hadoop and on a public cloud object store, with no code changes between environments. What would you abstract away?
    Technical depth · from the posting: “Design and implement a "build once, run anywhere" architecture supporting seamless deployment across on-premises and public cloud environments without code changes”
  2. A production ETL job built with DMExpress fails overnight and the data warehouse doesn't get refreshed before business hours. Walk me through how you triage this independently, since the posting says you need to handle incidents on your own.
    Scenarios & troubleshooting · from the posting: “Perform assigned tasks and production incident independently”
