1) Your daily batch in SAS fails randomly at 3 AM—how do you triage without guessing?

  • I first separate “data issues” from “platform issues” by checking upstream file footprints and last successful run sizes.
  • I review job logs for repeating warnings before the failure timestamp to spot creeping data anomalies.
  • I validate resource contention by correlating failures with other heavy jobs on the same server or grid node.
  • I compare the failing job’s input row counts vs. historical medians to flag sudden spikes or drops.
  • I check for environment changes (patches, access revokes, folder permissions) in the past 24–48 hours.
  • I re-run a minimal, read-only subset to confirm whether the crash is reproducible without writes.
  • I document a short incident note with root cause candidates and prevention ideas for CAB review.

2) Your stakeholder complains that SAS reports don’t match finance numbers—what’s your approach?

  • I align time windows first (posting date vs. transaction date vs. run date) to remove timing gaps.
  • I validate business rules (currency conversions, tax treatments, rounding) used in each system.
  • I reconcile level by level: total → segment → account → transaction to locate divergence quickly.
  • I evaluate late-arriving corrections and back-posted entries that the report window missed.
