What is prototyping experience?

This is not simple. Prototyping is an industry. I don’t know what the CNC you are doing is. Prototyping is for making models. The so-called prototyping machine operation experience means that you need to have done CNC in the prototyping industry. Experience in operating the machine, because CNC has a wide range of uses. It does not mean that knowing the CNC machine or being familiar with the machine system means knowing how to operate the CNC machine. The key is to see where the CNC you make is used, whether it is a mold, model, prototype, etc. Engraving and other industries, the other party is recruiting people who need experience in the prototyping industry! !
