Technical Skills

1. Can you explain the ETL process and its importance in data integration?

Understanding the ETL (Extract, Transform, Load) process is crucial for a Data Engineer, as it forms the backbone of data integration solutions.

How to Answer

Discuss the stages of ETL and their significance in ensuring data quality and accessibility for analysis.

Example

“The ETL process is essential for transforming raw data into a usable format. It involves extracting data from various sources, transforming it to meet business needs, and loading it into a data warehouse. This process ensures that data is accurate, consistent, and readily available for reporting and analysis.”
