I applied online. The process took 3 months. I interviewed at Amgen (Thousand Oaks, CA) in Jun 2016
Interview
I was contacted by HR within a week of submitting my resume. The HR interview was very encouraging and informative. The hiring process was very long, 3 months in fact. I went through 1 more round of phone interview and one on-site interview that last 3 hours. In the end, the role was offered to an internal employee.
