The process took 1 day. I interviewed at Discover in Jan 2008
Interview
Interested in sales experience, previous phone work. Seemed to be looking more for the way you handled yourself and your communications skills more than any particular experience. Mine was a job fair type environment, they screened everyone, then asked some people back for a more intensive interview. I would dress professionally, but not wear a suit. It is a pretty laid back business environment.
