Technical Skills

1. Can you explain the process of building a data pipeline from scratch?

This question assesses your understanding of data pipeline architecture and your practical experience in building one.

How to Answer

Outline the steps involved in building a data pipeline, including data ingestion, transformation, and storage. Highlight any specific tools or technologies you have used in the past.

Example

“I typically start by identifying the data sources and determining the best method for ingestion, whether it’s batch processing or real-time streaming. I then use tools like Apache Kafka for ingestion, followed by transformation using Azure Data Factory, and finally store the processed data in a SQL or NoSQL database, depending on the use case.”

2. What are the advantages of using Azure Data Factory for data integration?

This question evaluates your familiarity with cloud data integration tools.

How to Answer

Discuss the features of Azure Data Factory that make it a preferred choice for data integration, such as its scalability, ease of use, and integration with other Azure services.

Example

“Azure Data Factory offers a user-friendly interface for building data workflows and integrates seamlessly with other Azure services. Its ability to handle both batch and real-time data processing makes it a versatile tool for various data integration scenarios.”
