Technical Skills

1. Can you explain the difference between bronze and silver data in a data pipeline?

Understanding the data hierarchy is crucial for a Data Engineer, and this question tests your knowledge of data processing stages.

How to Answer

Discuss the definitions of bronze and silver data, emphasizing their roles in the data pipeline and how they contribute to data quality and usability.

Example

“Bronze data refers to raw, unprocessed data that is ingested from various sources, while silver data is the cleaned and transformed version that is ready for analysis. The transition from bronze to silver involves data validation and enrichment to ensure accuracy and reliability for downstream applications.”

2. Describe your experience with data extraction and transformation tools.

This question assesses your hands-on experience with the tools and technologies relevant to the role.

How to Answer

Mention specific tools you have used, your role in the data engineering process, and any challenges you faced during extraction and transformation.

Example

“I have extensive experience using Fivetran for data extraction and transformation.
