      Top 5 Technical Interview Questions Asked Back End Developer

      • Key Concepts: This question tests your understanding of database architectures. Relational databases (e.g., MySQL, PostgreSQL) use structured schemas and are ideal for applications requiring complex queries and transactional integrity. NoSQL databases (e.g., MongoDB, Cassandra) offer flexibility in handling unstructured data and are suitable for applications needing scalability and fast read/write operations without complex transactions.
      • Answer: Provide examples of scenarios where each database type is appropriate, such as using relational databases for financial systems and NoSQL databases for real-time analytics or big data applications.
      • Key Concepts: This question assesses your understanding of RESTful API design, which is central to back-end development. You should explain the principles of REST, such as statelessness, resource-based URL structures, use of standard HTTP methods (GET, POST, PUT, DELETE), and the importance of status codes.
      • Answer: Discuss best practices like using nouns for resource names, ensuring APIs are versioned, implementing pagination for large datasets, and including proper error handling and security measures like authentication and rate limiting.
      • Key Concepts: This question evaluates your ability to identify and resolve performance bottlenecks in databases. Common techniques include indexing, query rewriting, caching, and analyzing execution plans.
      • Answer: Describe steps you would take, such as checking the query execution plan to identify slow operations, adding indexes on frequently queried columns, optimizing joins, and reducing the number of database hits by caching results where appropriate.
      • Key Concepts: This question explores your understanding of concurrency and how asynchronous processing can improve the performance of a web application by freeing up resources while waiting for I/O operations (like database queries or API calls) to complete.
      • Answer: Explain that synchronous operations block the execution thread until the task completes, while asynchronous operations allow the application to continue executing other tasks. Discuss scenarios where asynchronous processing can improve user experience, such as handling file uploads or long-running tasks without freezing the user interface.
      • Key Concepts: This question assesses your knowledge of modern software architecture. Microservices involve breaking down a large application into smaller, independent services that can be developed, deployed, and scaled individually.
      • Answer: Discuss the benefits, such as improved scalability, flexibility in technology choices, and easier maintenance. Also, address challenges like increased complexity in managing inter-service communication, data consistency, and monitoring across services.
