Understanding the strengths and weaknesses of different database types is crucial for a Data Engineer.

How to Answer

Discuss the characteristics of both SQL and NoSQL databases, including their use cases, scalability, and data structure.

Example

“SQL databases are relational and use structured query language for defining and manipulating data, making them ideal for complex queries and transactions. In contrast, NoSQL databases are non-relational and can handle unstructured data, which is beneficial for applications requiring high scalability and flexibility, such as real-time analytics.”

2. Describe your experience with ETL processes. What tools have you used?

ETL (Extract, Transform, Load) processes are fundamental to data engineering, and familiarity with various tools is essential.

How to Answer

Highlight specific ETL tools you have used, your role in the process, and any challenges you faced.

Example

“I have extensive experience with ETL processes using tools like Apache NiFi and Talend. In my previous role, I designed a data pipeline that extracted data from multiple sources, transformed it to meet business requirements, and loaded it into a data warehouse. This improved data accessibility for analytics teams.”

3. How do you ensure data quality and integrity in your projects?
