The process took 4 months. I interviewed at Express Scripts in Jan 2010
Interview
be prepared to interview 15 rounds before they make up their mind. Sometimes, they don't know how to make a decision and then you will be passed on. They will call you again and put you through the same process. Very good company to work for, if you get an offer.
