Rishabh's response demonstrates a basic understanding of handling large datasets in Google Sheets. He mentions using filters, pivot tables, VLOOKUP, and other formulas, which aligns with the benchmark response. However, his explanation lacks depth and clarity, particularly in ensuring data accuracy and efficiency. He does not elaborate on maintaining data integrity or checking for errors, which are crucial for accurate analysis. To improve, Rishabh could provide a more structured approach and discuss specific techniques for error checking and data validation.
