I've done both inside/outsidepharma sales and like/dislike things about both positions. Obviously the rapport building aspect of outside sales is much stronger because of more points of contact and face to face expression. On the phone, dialogue is very limited, and you have to close for your objective very quickly before the gatekeeper or MA gets agitated because you are taking up time they could be checking in patients. There is something to be said, however, for the pure volume of activity that can be obtained inside vs. outside. I still believe if your product is a fairly technical sell, it's advantageous to be in front of the customer physically. I also found inside sales usually pays a little less, and there certainly a loss of autonomy, meaning you can't just create your own pace and schedule.
