Three of the questions

  1. Walk me through how you'd design a phishing or fraud anomaly detection pipeline that has to run over petabytes of data. Where does the ML model fit versus rule-based pattern detection, and how would you keep false positives manageable at Apple's scale?
    Technical depth · from the posting: “participate in building machine learning pipelines, phish/fraud/anomaly detection models”
  2. You're on-call for the payments platform and start seeing connection pool exhaustion errors along with a spike in slow queries against Oracle. Walk me through how you'd triage this live, in production, right now.
    Scenarios & troubleshooting · from the posting: “diagnosing connection pool exhaustion, stale connections, and slow queries”
  3. Apple's IS&T supports 2.5 billion active Apple devices and processes billions of secure transactions. Tell me about a time you had to work on a system at similar scale or complexity, and how you approached the challenge.
