Problem

Explain your proficiency in data analysis tools with a clear SQL focus. Center your answer on PostgreSQL and describe how you use it for customer insights work such as filtering records, aggregating KPIs, grouping results, and cleaning messy data before reporting. You may mention supporting tools used alongside Genesco reporting workflows, but the answer should stay grounded in SQL & data manipulation rather than broad analytics tooling.

What This Tests

  • Ability to speak concretely about PostgreSQL proficiency
  • Understanding of aggregations and GROUP BY in business analysis
  • Awareness of data wrangling tasks like NULL handling and standardization
  • Ability to position SQL alongside reporting or dashboard tools
