Understanding the differences between these database types is crucial for a Data Engineer, as it impacts data storage and retrieval strategies.

How to Answer

Discuss the fundamental differences in structure, scalability, and use cases for SQL and NoSQL databases. Highlight scenarios where one might be preferred over the other.

Example

“SQL databases are structured and use a predefined schema, making them ideal for complex queries and transactions. In contrast, NoSQL databases are more flexible, allowing for unstructured data storage, which is beneficial for applications requiring scalability and rapid development.”

2. Describe a complex SQL query you have written. What was its purpose?

This question assesses your practical experience with SQL and your ability to handle complex data manipulations.

How to Answer

Provide a specific example of a SQL query you wrote, explaining the context, the data involved, and the outcome of the query.
