Interview questions [1]
Question 1
ETL is a process for extracting data from source systems, transforming it into a structured format, and loading it into a destination system (e.g., a data warehouse). It's crucial because it helps cleanse, enrich, and organize data for analysis, making it ready for use by data professionals.
