I am an industry vet. I have been selling in diabetes for 15+ years. I am going to give you the straight scoop. You are in a good therapeutic area! Diabetes is great as far as job security goes b/c the disease is at epidemic rates here in the US.
However; don't be fooled, your DM is likely not as nice as you think. Most people in this industry who are promoted into management are pretty savvy. They may have stepped over (or on) many others to get where they are.
Also some other things to keep in mind...your boss could have hired an out of work industry vet. Why didn't he? Because
-you are cheaper
-you are young and therefore not as intimidating
-you have passion
I sell insulin and my pompous DM told me he wouldn't even consider hiring anyone w/o 2 yrs diabetes pharma experience. I think he is just too lazy to take the time to train a newer rep, but think about why your DM hired you. Perhaps you have a new(er) manager or more likely a DM with a big ego + little self-confidence. Either way, your DM is someone who couldn't handle a seasoned vet.
They were impressed with your doe eyed passion and energy. This will wear off. Don't EVER let your DM know you are anything other than the perky sycophant he hired! Even in 6 months when you realize that all the docs are ambivalent and really don't treat diabetes with the urgency it deserves. Slap on that smile girlfriend and kiss your DMs butt. THAT is your value and that is why you were hired! Keep playing that part and you can have a good 3-5yr run.
Get your CDE, if the company pays for it. Many companies have educator jobs that are not sales. Keep up your RN license/CEUs, so you have that to fall back if ObamaCare ruins the whole pharma industry. Get your NP if you can. Just know, that this industry has downsized by 40% in the last few years, so don't get too accustomed to the money. It will not always be there. Put some money away and make a 3-5 year plan for yourself.
Also, you will at some point experience negativity from your co-workers. They know that they you are their replacement. When things go to hell, they will be the ones who are laid off, NOT you (because you are cheaper and you are little miss sunshine). They may take their frustrations out on you. Just let it roll off your back. It is not YOU, it is just the situation you are in. Keep the positive attitude. Make the most of this opportuity for you and your future! Good luck!
