I applied through a recruiter. The process took 2 weeks. I interviewed at Amgen (Thousand Oaks, CA) in Nov 2012
Interview
Interview process is very regress . Normally multiple rounds with group or panel. Many times it is phone screening followed by in person interview. Sometime it is more than one round of phone screen before they get you in for face to face.
Interview questions [1]
Question 1
