NoSQL
A category of databases that don't use the traditional table/row structure of SQL — better suited to flexible or rapidly changing data shapes (e.g. MongoDB, DynamoDB).
Think of it like
Like a flexible filing cabinet where each folder can hold whatever mix of documents it needs, instead of a rigid form every file must fit.

Chose NoSQL because it's what they were familiar with.
Senior sounds like
Can explain the specific reason NoSQL was the right call over a relational database for that use case.
Ask them
“Tell me about a time you chose (or would choose) a NoSQL database over a relational one, and why.”
