this like for most biotech jobs out there, its why most people dont go into bio/tech research foot in the door they first put up that barrier as a listing , and it becomes a catch-22, its a law of diminishing returns for the industry. plus they also have preference of which "group" they will hire. im not surprised theres a bait and switch. dont know how often bio uses linkedin, but ive seen people have thier profiles for thier bio experiences if they are in that industry.
