Preparing for a software programming interview can be challenging. This repository aims to provide a comprehensive collection of interview questions and answers that cover essential programming concepts and topics. Whether you are a beginner or an experienced developer, you will find valuable resources here to aid your interview preparation.
- What is a variable in programming?
- A variable is a storage location identified by a name that holds data which can be modified during program execution.
- Explain the difference between == and === in JavaScript.
- checks for equality of value, whereas === checks for both value and type equality.
- What is a loop? Provide an example.
- A loop is a control structure that repeats a block of code while a condition is true. Example: for (int i = 0; i < 10; i++) { console.log(i); }
- What is object-oriented programming (OOP)?
- OOP is a programming paradigm that uses objects and classes to model real-world entities and relationships.
- Explain the concept of a database transaction.
- A database transaction is a sequence of operations performed as a single logical unit of work, ensuring data integrity and consistency.
- What are RESTful APIs and why are they used?
- RESTful APIs are web services that follow the REST architectural style, allowing interaction with web resources using HTTP methods. They are used for creating scalable and maintainable web services.
- Describe the differences between a microservices architecture and a monolithic architecture.
- Microservices architecture breaks down an application into smaller, independent services, whereas monolithic architecture consolidates all functionalities into a single codebase.
- What is the purpose of dependency injection in software design?
- Dependency injection is a technique for achieving Inversion of Control (IoC) by passing dependencies from the outside rather than creating them inside the class, promoting loose coupling and easier testing.
- Explain the concept of a deadlock and how to prevent it.
- A deadlock is a situation where two or more threads are blocked forever, each waiting on the other to release a resource. Prevention methods include resource ordering, timeout, and deadlock detection algorithms.
