Was contacted by a headhunter and put in touch with the hiring manager. There were a couple of mis-fires getting connected (missed calls, etc) but finally did speak on the phone for 45min or so. About 30min was him asking me about my experience, then 15min or so for me to ask questions. Then did a phone interview with an HR contact. Then a full day of in-person interviews with 6 people across departments and within the group I'd be hired into. Nothing out of the ordinary, just questions about my experience, why BioGen, etc.
