The scheme proved to be effective in preventing failures and disruptions in the power plant.
• 8. How do you troubleshoot a fault in a protective relay?
  Answer: First, I analyze the relay settings and compare them with the fault record. Then, I check for loose connections, incorrect settings, or any other issues that may have caused the fault. If needed, I perform simulations or tests to further narrow down the problem. I document my findings and propose a solution to fix the issue.
• 9. Can you explain how you ensure proper coordination between protective relays?
  Answer: Coordination between protective relays is crucial to ensure the correct relay operates in case of a fault. I use software tools to simulate the network and adjust the relay settings, taking into consideration the time and current coordination. I also perform testing and commissioning of the relays to ensure they are functioning correctly.
• 10. Have you worked on any projects involving renewable energy sources? If so, can you describe your role?
  Answer: Yes, I have worked on a solar energy project where I was responsible for designing and implementing the protection system for the solar panels and inverters. I also worked on developing a communication network between the solar farm and the grid to ensure smooth integration and operation.

Decision-Making & Problem-Solving

• 11. How do you prioritize and handle multiple projects simultaneously?
  Answer: I start by carefully assessing each project's requirements, deadlines, and resources. Then, I prioritize them based on their urgency and complexity. Throughout the projects, I continuously review and adjust my priorities based on any changes or challenges.
• 12. Can you give an example of a difficult problem you encountered on a project and how you solved it?
  Answer: In one project, we encountered unexpected issues with the installation of protective relays due to compatibility issues between different manufacturers' equipment. I worked closely with the team to analyze the problem and propose a solution that involved reconfiguring the network to support the relays and updating the communication protocol. This allowed us to successfully install the relays and prevent further delays in the project.
• 13. How do you handle conflicts or disagreements with team members or stakeholders?
  Answer: I believe in open communication and active listening. I try to understand the other person's perspective and find a middle ground that benefits both parties. If needed, I involve a mediator or approach the issue diplomatically to reach a resolution.
• 14. Describe a time when you had to make a quick decision in a high-pressure situation.
  Answer: In one project, we encountered a sudden power outage due to a fault in the grid. I had to quickly assess the situation, prioritize the affected equipment, and coordinate with the team to troubleshoot and restore power. Through swift decision-making and effective teamwork, we were able to successfully restore the power within a short timeframe, minimizing disruptions for our clients.
• 15. How do you ensure the safety of yourself and others while working on electrical equipment?
  Answer: Safety protocols and procedures should always be followed while working on electrical equipment. I always ensure the equipment is de-energized before starting any work, wear appropriate protective gear, and carefully analyze the potential hazards before proceeding with any task. I also regularly check and maintain equipment to prevent any safety risks.

Cultural Fit

• 16. How do you handle a situation where a team member is not meeting their deadlines?
  Answer: I believe in clear communication and setting realistic expectations from the beginning. If a team member is struggling to meet their deadlines, I approach them with understanding and try to identify any underlying issues that may be causing the delay. I then work with them to find a solution that helps them meet their deadlines without compromising the project's quality.
• 17. Describe a time when you had to work with a difficult client or stakeholder.
