• 6. Can you explain the difference between object-oriented programming and functional programming?
  Object-oriented programming is a programming paradigm that focuses on creating objects with attributes and methods to solve problems. On the other hand, functional programming is a programming style that treats computation as the evaluation of mathematical functions and avoids changing the state of data. Both approaches have their advantages, and I am comfortable working with both paradigms.
• 7. Have you worked with databases before?

• 9. Can you describe a project where you had to troubleshoot and fix a complex bug?
  In a previous project, I encountered a bug that was causing a significant decrease in performance. After analyzing the code and using troubleshooting techniques, I identified the issue in a third-party API integration. I fixed the bug by implementing a cache mechanism, which significantly improved the software's performance.
• 10. How do you approach testing your code?
  I believe in incorporating testing throughout the software development process. I write unit and integration tests using frameworks like JUnit and Mockito and perform manual and automated regression testing. I also collaborate with QA engineers to ensure comprehensive test coverage.
• 11. How do you prioritize tasks when working on multiple projects simultaneously?
  I prioritize tasks based on their impact on project timelines and deliverables. I also consider the dependencies and criticality of tasks and communicate with my team and stakeholders to set realistic expectations and deadlines.
• 12. Can you tell us about a time when you had to quickly learn a new programming language or framework?
  In a previous role, I was assigned to a project that involved working with a new programming language and framework that I was not familiar with. I immediately started learning through online resources and completed the project within the deadline, exceeding expectations. This experience has taught me the importance of adaptability and continuous learning in the technology industry.

  I believe in open and honest communication and actively listening to all viewpoints. I also focus on finding a solution that benefits the team and the project as a whole.
• 14. Have you ever implemented a new technology or process in a development team? If so, how did it go?
  Yes, I have successfully introduced a new deployment process in a development team that improved code quality and reduced errors. I collaborated with team members to explain the benefits and provided training to ensure a smooth transition.
• 15. How do you handle tight deadlines and high-pressure situations?
  I have experience working under tight deadlines and high-pressure situations, and I have learned to stay calm and focused. I prioritize tasks and break them down into smaller, manageable chunks to ensure timely delivery. I also communicate effectively with my team and stakeholders to reset expectations if necessary.

Behavioral Questions

• 16. Can you tell us about a time when you collaborated with a team member to solve a difficult coding problem?

• 17. How do you handle criticism or negative feedback on your code?
  I am always open to constructive criticism and feedback, as it helps me improve as a developer. I take the time to understand the feedback and incorporate it into my future work.
• 18. Have you ever faced a project where you had to go above and beyond to deliver the desired outcome?
  I believe in giving my best effort in every project I work on, but there was one project where I had to put in extra hours to meet the deadline. It was a challenging experience, but the satisfaction of delivering a high-quality product made it worth it.
• 19. Can you tell us about a time when you had to adapt to a new team or project quickly?
  In my previous role, I was transferred to a new project that was already in progress. I had to quickly learn about the project requirements, codebase, and team dynamics. I took the initiative to reach out to team members for guidance and completed my tasks effectively, earning the trust of my team.
