I applied through an employee referral. The process took 1 day. I interviewed at Advanced Clinical Research (ACR) (Boise, ID) in Aug 2016
Interview
You often only get called in for an interview if you were referred by someone who works there. Come in for an onsite interview with the cite director. She basically tells you her life story and asks very little questions of you. It's an extremely easy process, probably because you are most likely a referral and so you go in to the interview already having the job.
