When answering this question, focus on a specific instance where you identified and resolved a materials-related issue in a manufacturing process. Start by briefly describing the context and the problem. Then, explain the steps you took to troubleshoot the issue, including any analysis or testing methods you used. Highlight your thought process, the tools or techniques you employed, and how you collaborated with other team members if applicable. Conclude with the outcome and any lessons learned. For example:
"In my previous role, we encountered an issue with the tensile strength of a new alloy we were testing for automotive parts. I led the investigation by first reviewing the production process and identifying potential points of contamination. I then conducted a series of tests, including X-ray diffraction and scanning electron microscopy, to pinpoint the exact cause. After identifying a specific impurity in the raw materials, I worked with our supplier to rectify the issue and implemented additional quality control measures. As a result, we improved the alloy's performance and reduced production downtime."
