I applied through an employee referral. The process took 2 weeks. I interviewed at Express Scripts (Saint Louis, MO) in Aug 2012
Interview
Lots of behavioral questions, they always ask those, and they're all based on their six "express way" values. Sometimes they ask off-the-wall questions just to throw people off, like "how many rubber balls would you use to fill a 11 x 11 foot room"? There's no right answer they just want to stress people out.
