Sample answer
“At my previous internship at IBM, I worked on integrating a legacy CRM system with a new cloud-based solution. The biggest challenge was data inconsistency between the two systems. I collaborated with the data team to establish a mapping strategy and used ETL tools to ensure data integrity. As a result, we successfully migrated 95% of the customer data without major issues, improving data access for the sales team by 30%. This experience taught me the importance of thorough planning and communication.”
