I was contacted by recruiters of a staffing agency. They were hiring a QSP Scientist to work for Bristol-Myers Squib in Lawrenceville, NJ. They sent me a job description and I had a chat with them on the phone. They were not able to answer any questions related to the job responsibilities but put a lot of effort in trying to negotiate a salary (I would say this was the main goal of the chat for them). I would describe the overall process as unprofessional.
