Gagan's response to the question about automating a weekly IT infrastructure utilization report in Google Sheets was inadequate. He simply stated, "Sorry I don't know," which indicates a lack of understanding or experience in this area. The benchmark response outlines a detailed approach involving data source identification, data extraction, use of Google Sheets functions, and automation with Google Apps Script. Gagan could have improved his response by discussing any similar experiences or demonstrating knowledge of Google Sheets' capabilities and automation techniques.
