Interview Question:
Explain the difference between SQL and NoSQL databases.
How I Answered:
I explained that SQL databases store data in tables with predefined schemas and use SQL for queries, while NoSQL databases store data in flexible formats such as documents, key-value pairs, or collections. I also mentioned that SQL databases are generally preferred for complex transactions, whereas NoSQL databases are often used for scalability and handling unstructured data.

Interview Question:
What is the difference between state and props in React?
How I Answered:
I explained that props are used to pass data from a parent component to a child component and are read-only, whereas state is managed within a component and can be updated to trigger re-renders.
Since you mentioned the interview was very basic, either of these would fit well.
