Tanmay's response indicates a basic understanding of SQL query optimization but lacks depth and specificity. He mentions avoiding select queries and subqueries, using indexes, and leveraging cloud databases, but does not elaborate on how these strategies would be implemented or their impact on performance and accuracy. The response could be improved by discussing the use of WHERE clauses, CTEs, and data validation checks, as well as integrating results with Power BI for visualization, as outlined in the benchmark response.
