Had three phone screenings then an on-site interview. On-site they put me in a small conference room where I stayed while visited by six different interviewers. Lasted most of the day. They provided lunch. One interviewer was by phone because he was out of the country. The first interviewer was the Director, then two middle managers, a project lead, a senior engineer, and finally an HR person. Questions were ranging from technical and behavioral to strategical and career planning. I researched all interviewers and asked pointed questions, but in most cases I did not have time to ask all the questions that I had prepared. There were several positions open, so I wasn't sure which one I was being interviewed for. It seemed that the hiring managers were trying to get a sense of what my career goals were. BD has a complex career progression structure, and it seems that employees move around within departments every few years. It took me some time to understand the career pathways as they described them. They kept asking where I thought I might fit in. I have a broad range of experience and a doctorate, so it was difficult to pigeon hole myself into one of their career tracks. I thought the interview went well, but I suppose they couldn't figure out how to fit me into their structure or I was lacking in very specific skills.
