What is a media query in CSS used for in responsive design?

  • To apply different styles based on device characteristics
  • To create animations in the CSS code
  • To define variables in the CSS code
  • To embed media files in the CSS code
A media query in CSS is used to apply different styles based on device characteristics such as screen width, height, or device orientation. It allows developers to create responsive designs by adapting styles to different devices.

What is Test-Driven Development (TDD) primarily focused on?

  • Code optimization
  • Ensuring code quality through testing
  • User interface design
  • Writing tests after code implementation
Test-Driven Development (TDD) is primarily focused on ensuring code quality through testing. In TDD, tests are written before the actual code implementation, and the development process revolves around making these tests pass. This approach helps catch bugs early and ensures that the code meets the specified requirements.

A client wants their website to be accessible on all devices without compromising user experience. How would you approach this requirement in your responsive design?

  • Conduct thorough testing on various devices
  • Employ fluid grid layouts
  • Implement responsive breakpoints
  • Use a mobile-first approach
A mobile-first approach ensures that the design starts with the smallest screens, providing a solid foundation for responsiveness across all devices.

You're working on an application that requires efficient handling of real-time data streams. Which data structure and algorithmic approach would you employ?

  • Circular Buffer with Sliding Window
  • Linked List
  • Recursive Descent Parsing
  • Stack Data Structure
A Circular Buffer with a Sliding Window is effective for handling real-time data streams. It allows continuous data processing with constant time complexity, making it suitable for scenarios where data arrives in a continuous stream.

What is the purpose of a pull request in version control systems like Git?

  • Checking out code
  • Committing code directly
  • Creating a new branch
  • Merging code changes
