My resume was passed along to the hiring manager by someone in her group who was acquainted with someone I knew in grad school. I had way less experience than they were looking for (0 yrs instead of 8+ yrs), but they were willing to interview someone without the management experience who still had the right science qualifications. A few weeks after I submitted my resume, I got an email to set up a phone interview. The phone interview was 25 min long and mostly consisted of the hiring manager telling me about the position. At the end of the phone interview, she asked to set up an on-site interview. We decided to discuss possible dates for the interview over email. HR was very slow about getting back to me regarding interview dates, so some of the organizing was done through the hiring manager as well. The interview consisted of three meetings with 6-8 people total in the morning, followed by a lunch-time seminar. People interrupted (not in a rude way) and asked questions during the seminar, so the seminar was something of a discussion. I had lunch with one person in the cafeteria, then additional interviews with higher level people in the afternoon. Overall the experience was very positive. The interviewers were genuinely interested in my research, and were very open about their experiences working at Biogen. With the exception of one interviewer, everyone seemed to love working at Biogen.

Two rounds of full day interviews with total of 10 people (From Associates to VPs). Very good experience. Got lots of information about company. Got an offer and accepted it. BUT got my foot in first through "networking".
