  Object-oriented programming focuses on objects and their interactions, while functional programming emphasizes on functions and their output without altering the input. Object-oriented programming is more suited for large-scale projects, while functional programming is useful for tasks like data manipulation.
• 10. How do you approach debugging when encountering an error in your code?
  I start by checking the error logs and tracing the code to identify the cause. If I am unable to find the solution, I consult with my team or use debugging tools to step through the code. I also make sure to document the error and solution for future reference.

Decision-Making & Problem Solving

• 11. How do you prioritize tasks when working on multiple projects simultaneously?
  I first determine the project timelines, priority level, and potential impact. Then, I break down the tasks and allocate time for each based on their complexity and urgency. I also communicate with my team and ask for assistance when needed.
• 12. Can you think of a creative solution you implemented to solve a coding problem?
  In a project, I needed to manipulate a large dataset but faced limitations with the available memory. After brainstorming with my team, we came up with the idea of dividing the data and processing it in parallel, significantly reducing the execution time and memory usage.
• 13. How do you handle a disagreement with your team members on a design or approach?
  I believe in constructive communication and strive to understand the reasoning behind their perspective. If we are unable to reach a consensus, I bring in a neutral party, such as a project manager, to make a decision. I also make sure to maintain a positive working relationship with my team members.
• 14. Can you give an example of a time when you had to quickly adapt to a change in project requirements?
  During a project, the client requested a last-minute change that required a different approach. I immediately consulted with my team and identified the areas that needed modifications. I also kept an open line of communication with the client and made sure to deliver the updated project within the deadline.
• 15. How do you handle a coding error in a critical system?
