Getting out of Pharma is not impossible, but it is not easy. The biggest problem you have is the fact that a lot of businesses hired Pharma reps in the past 5 years and most have been a disappointment. Please don't flame me on this point. Your basic Pharma rep is lazy and does not know how to sell. Ask yourself if you know what a sales cycle is. How do you negotiate the terms of a contract? How do you assess a market, determine the multiple layers of stakeholders and decision makers, and the access those people to drive a sale? You haven't been trained in this type of selling, and it will hurt you on your interview.
The good news is the pressure that Novartis puts on you is fabricated. The stuff that Novartis Management cares about is laughed at in the rest of the business world. A sales manager in a sales company is a resource to help you drive your sales. For the most part they leave you alone if you know what you are doing. You can call on them as needed to help you with a customer or to get resources from the company.
The other piece of good news is that your quotas are generally fair and attainable. Sales companies do not look at their sales representatives as interchangeable. They recognize that the rep has value and can take the business with them to a competitor, so they ensure that the quotas are fair. They are not easy, but they are attainable, and you are rewarded for achieving them.
To get a job outside of pharma, look for related medical sales types of companies. Don't just think about device or capital equipment. Look at any industry that touches the medical community. You may have to start in a business that is not your first choice to prove that you are not the typical lazy, non selling pharma person they may have met in the past. Again, I am not trying to insult you, but I am telling you how you will be viewed. If you do the work, you can make it out.
