In my previous role, I was responsible for designing HVAC systems for commercial buildings. I led a team to assess client requirements, develop system specifications, and create detailed designs using software like AutoCAD and Revit. We also conducted thorough feasibility studies and collaborated with contractors to ensure smooth implementation of the systems." Approach to problem-solving: "When faced with a problem, I first analyze the root cause by gathering data and conducting thorough research. I then brainstorm potential solutions, considering factors such as feasibility, cost-effectiveness, and impact. I prioritize solutions based on their potential to address the issue effectively and efficiently, and I'm always open to feedback and collaboration to refine the solution further."
