I am comfortable sharing a sample dataset so you can map the fields, clean anomalies, and transform the numbers. Ideally the workflow is automated—SQL or Python for the heavy lifting and Excel, Power BI or Tableau for the final dashboards and printable summaries—but I am open to whichever stack you can justify as robust and maintainable....

    For the next round of hiring I want an accomplished Senior Data Engineer to sit in on our technical interviews for roughly two hours each day.
