Sample answer
“When sanding drywall, I start by using a coarser grit sandpaper to remove any bumps or imperfections. I then switch to a finer grit to achieve a smooth finish. I always sand in a circular motion and keep an eye out for dust buildup, which I remove before continuing. After sanding, I inspect the surface under good lighting to ensure it’s perfectly smooth. I also wear a mask and goggles to protect against dust inhalation and irritation, ensuring a safe work environment.”
