I applied through an employee referral. The process took 1+ week. I interviewed at Kaiser Permanente (Oakland, CA) in Sept 2014
Interview
Very friendly and straightforward. Basic questions you will expect in just about every interview. Not too technical and more interested in the kind of projects you have worked on and methods/software you used in them.

Interview
Get a phone call from HR and just general interview questions. A few questions about work experience. Questions about future plan and some tech questions about statistician. The HR is really nice to talk with.
