I also made sure to be patient and answer any questions they had. By the end of the training, they were able to use the software independently.

Situational Questions

• 6. If a client requests a feature that is not feasible within the given timeline, how would you handle the situation?
  Answer: I would communicate the feasibility and limitations of the request to the client. If possible, I would suggest alternative solutions that could be implemented within the given timeline and explain the impact of the requested feature on the overall project. Ultimately, the decision would be made in consultation with the team and the client.
• 7. How would you handle a project that has conflicting priorities and urgent deadlines?
  Answer: I would prioritize tasks based on their importance and urgency and communicate with the project manager to re-allocate resources if needed. I would also keep the team updated and delegate tasks appropriately to ensure timely completion of all tasks.
• 8. If given the choice, would you prefer to work on a new project or an existing project, and why?
  Answer: I enjoy working on both, but if I had to choose, I would prefer a new project. It allows me to explore new technologies, learn new skills, and be a part of the project from the ground up. However, I am also comfortable working on existing projects and making improvements to enhance their functionality.
• 9. How do you handle a situation where you are unable to meet a project deadline?
  Answer: I prioritize tasks and try my best to meet deadlines. However, if I am unable to do so, I inform the project manager immediately and provide a realistic timeline for completion. I believe in being transparent and keeping stakeholders updated on the progress of the project.
• 10. If a client requests changes to the project's scope, how would you handle it?
  Answer: I would first assess the feasibility and impact of the requested changes on the project's timeline and resources. If the changes are not feasible, I would communicate the limitations to the client and propose alternative solutions. If the changes are feasible, I would communicate the impact on the timeline and resources and get approval from the project manager before implementing them.

Technical Questions

• 11. What programming languages are you proficient in?
  Answer: I am proficient in Java, Python, and C++. I have also worked with HTML, CSS, and JavaScript for front-end development.
• 12. Can you explain object-oriented programming?
  Answer: Object-oriented programming is a programming paradigm that focuses on creating objects that have properties and methods. These objects can interact with each other to solve complex problems and create modular, reusable code.
• 13. Explain the difference between a class and an object.
  Answer: A class is a blueprint for creating objects, while an object is an instance of a class. A class defines the attributes and behaviors that will be shared by all objects of that class, while an object is a specific representation of that class with its own unique values for its attributes.
• 14. How do you handle error handling in your code?
  Answer: I use try-except blocks to handle exceptions in my code. I identify potential errors and use the appropriate exception handling techniques to handle them, such as displaying user-friendly error messages or logging the error for debugging purposes.
• 15. What is the difference between a list and a tuple in Python?
  Answer: A list is a mutable data structure, while a tuple is an immutable data structure. This means that you can change the values of a list, but not a tuple. Lists are denoted by square brackets, while tuples are denoted by parentheses.
