Your interviewer will likely ask you knowledge-based questions to understand how well you are able to explain concepts to others. Be prepared for questions like this one by practicing a few possibilities ahead of time. In this case, cold working refers to processing a metal below its recrystallization temperature, which is usually one-third to one-half of the melting point. To do so, a high amount of pressure is applied in one of four general categories: squeezing, bending, shearing, and drawing. Doing so generally improves a material's tensile strength while reducing its ability to deform without breaking, also known as ductility. It can also be a way to shape metals into plates, sheets, and rods that are then used in manufacturing processes like machining.
