Interview process is extensive and thorough. Initial interview is with HR on the phone, followed by panel interviews, then final interview with several people in San Francisco. Usually requires a presentation for final interview.
I applied online. The process took 4 weeks. I interviewed at Genentech in Jun 2011
Interview
Phone interview with hiring manager then brought in for 1 on 1 interviews with about 8 other people. Long day. People were all very nice but i got the feeling they were willing to hire a less experienced person so they would stay in the same position for a long time.
