I've seen and hired many people in your position in the past. Not having a sales background can certainly make this a difficult task for you. However, there are a decent amount of device companies that offer "clinical sales" positions where its kind of a pseudo sales/clinical role where you still call on accounts in the field. Once a "clinical field rep" cuts their teeth and can show that they have what it takes, they can later get promoted into a medical device sales role depending on the company. Pharma is a whole different story, but is probably more likely than medical device even though it pays less money. Hope that helps you?
