When answering this question, it's important to demonstrate your systematic approach to problem-solving and your deep understanding of polymer science. Start by explaining the general steps you take when faced with an issue, such as identifying the problem, gathering data, and analyzing the information. Then, provide a specific example from your past experience where you successfully troubleshooted an issue in polymer research and development. Highlight the methods and techniques you used, such as spectroscopy, chromatography, or rheology, and explain why you chose them. Conclude by discussing the outcome and what you learned from the experience.
Example: "When troubleshooting issues in polymer research and development, I start by clearly defining the problem and gathering all relevant data. For instance, in my previous role, we encountered an unexpected decrease in polymer tensile strength. I collected samples and used spectroscopy to identify any chemical changes. I also performed rheological tests to understand the material's flow properties. After analyzing the data, I discovered that a slight variation in the polymerization temperature was causing the issue. By adjusting the temperature control process, we were able to restore the polymer's properties. This experience taught me the importance of thorough data analysis and the need to consider all variables in the production process."
