SDN Members don't see this ad. (About Ads) I had an interview for a job at CVS and they asked me why I want to work for CVS in comparison with other retail pharmacies, for example Walgreens. The only pharmacy I've had the opportunity to shadow in was Osco. Anyone know the main differences between CVS and it's competitors? I have another interview in another week or so and I bet they'll ask me this again.
