Sales are the ultimate barometer for measuring the success of a product. No matter how well the product is designed and manufactured, it isn't successful if it doesn't sell. The responsibilities of a product specialist extend beyond just the design and production of a product. You must work closely with the sales and marketing organization to ensure that the product meets the needs of the targeted customers, is priced competitively, and is distributed appropriately. You should be able to provide the interviewer with several examples of how you contributed to increasing the sales of products, including recommending some product improvements.
