If have an interview already set up: understand the product philosophy before the product himself! No need for sales lists of characteristics. They are not important for a PM position. How your product chain works: concept, design, simulations and sales approach. The entire supply chain from the engineer point of view.

Otherwise if you don't have the interview you can go trow a recruiter but normally you need further sign of NDA or something if is a global company. Let me if appreciate the synthetic answer.
