Monthly reporting is usually less about one complex query and more about building a repeatable set of SQL checks, summaries, and outputs that stakeholders can trust. Interviewers want to hear how you structure that work, not just whether you can write a single aggregation.
Explain your process for building a monthly reporting package in PostgreSQL. Walk through how you define the reporting month, validate source data, create monthly rollups, handle nulls or late-arriving records, and make sure the final output is consistent from month to month. If helpful, describe how you would prepare summary tables or exports that feed an IPG Health finance reporting deck.
Keep your answer practical and SQL-focused. You do not need to discuss advanced pipeline architecture. The interviewer is mainly looking for a clear workflow that uses sound date filtering, aggregations, and data-wrangling habits to produce reliable monthly outputs.
