Example:
"In my previous role at XYZ Company, I was responsible for selecting materials for a new line of consumer electronics. I evaluated various polymers and metals based on their mechanical properties, cost, and environmental impact. I chose a high-strength polymer that met all the performance requirements while being cost-effective and recyclable. I also ensured that the material complied with industry standards such as RoHS and REACH. This selection process involved close collaboration with the design and manufacturing teams to ensure the material could be easily integrated into the production process."
