Sample answer
“In my previous role at a foundry in Barcelona, I would start by selecting high-quality sand and ensuring it is properly mixed with the binder. I then used a vibrating table to compact the sand evenly. I always checked the dimensions against the specifications before pouring the metal. This meticulous process led to a 15% decrease in casting defects, which significantly improved our production efficiency.”
