Situational interview questions

  • You have been assigned to install a new electrical panel, but upon arrival at the worksite, you find that the panel is not compatible with the existing wiring. How would you solve this problem?
  • During a routine inspection, you discover that a wire is frayed and has the potential to cause a safety hazard. However, you do not have a replacement wire available at the moment. What would you do in this situation?
  • You are tasked with installing a new lighting fixture in a poorly lit area of a construction site. However, the installation requires a specific tool that you do not have readily available. How would you approach this situation without delaying the project?
  • While working on a complex wiring project, you encounter an unexpected wiring issue that is difficult to troubleshoot. What steps would you take to identify and resolve the problem?
