The main thing they asked me was about SAP and ERP. They asked me to explain what ERP is and how SAP is related to it. I explained that ERP (Enterprise Resource Planning) is a software system used by organizations to manage and integrate core business processes such as finance, human resources, sales, supply chain, manufacturing, and customer relationship management in a centralized manner. ERP helps organizations improve efficiency, reduce redundancy, and ensure real-time data availability across departments.
