Have you had experience working with NoSQL databases?

Questions about experience with NoSQL databases relate to practical experience rather than technical theory.

NoSQL databases differ from relational ones in that they do not use fixed schema tables but store data as documents, key-value pairs, graphs, or columns. Examples of popular NoSQL databases include MongoDB, Cassandra, Redis.

If you have experience, you can mention which databases you have worked with, what tasks you have solved, for example:

• Used MongoDB for storing JSON documents in a C++ project via drivers.
• Worked with Redis for data caching and speeding up access.

If you have no experience, you can say that you are familiar with the concepts of NoSQL and their differences from SQL, and are ready to learn and apply them if necessary.
