An example of an AI chatbot conversation about common backend interview questions.
What are some common backend interview questions I should prepare for?
Some common backend interview questions include: 1. What is RESTful API? 2. Explain the difference between SQL and NoSQL databases. 3. How do you handle authentication and authorization?
Can you explain the difference between SQL and NoSQL databases?
Sure! SQL databases are relational and use structured query language for defining and manipulating data. NoSQL databases are non-relational and can store unstructured data, making them more flexible for certain applications.
What is a RESTful API?
A RESTful API is an application programming interface that adheres to the principles of REST (Representational State Transfer). It uses standard HTTP methods like GET, POST, PUT, and DELETE to interact with resources.
How do you handle authentication in a backend application?
Authentication can be handled using methods like JWT (JSON Web Tokens), OAuth, or session-based authentication, depending on the application's requirements.
