One reason its getting harder to find a product design position

We product designers (even though it's not what I do to earn my crust, I still have a product designers heart) are a relatively rare bunch, that is to say that compared to graphic designers etc we are in the minority, but we are still here.  So when searching for jobs, how irksome it is to look at lots of job listings that say 'designer wanted' to then visit the description to find the company want a graphic designer or a costume designer or any other designer other than a product designer.   The latest is jobs advertised for NPD. Not so long ago, NPD (New Product Development) seemed to be mainly focused on product design. Now NPD seems totally related to designing and working within the foods industry, creating the latest ready meal.  Since when did the food industry bag it and why can they not call it something like NPDF.  There are so many disciplines that have designer as their following word, costume, set, graphic, car, lighting, to name but a few.  Why can’t the people writing the job descriptions not be more specific.  Surely this would achieve a better hit rate in terms of applicants as people scanning the job listings would know exactly what the job advertised was for?  Ok rant over.
