Server-Side Developer interview questions

Server-side development involves the backend logic and database interactions, whereas client-side development is focused on the user interface and experiences in a web browser.

I ensure security by following best practices such as validating input, using prepared statements, implementing authentication and authorization, and keeping the server and dependencies updated.

Common languages for server-side development include Java, Python, Ruby, PHP, JavaScript (Node.js), and C#.

I manage and optimize performance by using caching strategies, database indexing, optimizing queries, and employing asynchronous processing where applicable.

RESTful services are APIs that follow the REST architectural style, using standard HTTP methods. I implement them by designing endpoints that perform CRUD operations and return responses in JSON or XML format.

I have experience with both SQL databases like MySQL and PostgreSQL, and NoSQL databases like MongoDB, using them for data storage, retrieval, and complex querying.

My approach involves replicating issues in a development environment, using logging and debugging tools to trace problems, and systematically isolating and fixing the root cause.

I use libraries and frameworks for authentication, such as OAuth, JWT, or custom solutions, and implement role-based access control for authorization.

I prefer frameworks like Express.js for Node.js, Django for Python, and Spring Boot for Java because they provide robust features, community support, and make code maintenance easier.

I use migration tools or ORM features provided by frameworks to handle database schema changes, ensuring data consistency and integrity during migration.
