ETL Assessments for ETL Developer

ETL (Extract, Transform, & Load) is the process performed in the data warehouse. It involves the extraction of data from multiple data sources (relational database), a transformation of data into a suitable format & then loading the transformed data into the destination system (another database, file, data warehouse). An ETL developer is responsible for implementing the ETL process effectively to gather data warehouse information from unstructured data. It is then used by business users & senior authorities to form critical business decisions.

ETL assessments help tech recruiters and hiring managers to gauge developers' database engineering skills before hiring/recruiting. The ETL assessment test is designed & validated by experienced Subject Matter Experts (SME) to assess and hire ETL developers as per industry standards.
