Until last year, BSX had three levels of reps: Territory Mngr (TM), Account Mngr (AM) and Clinical Specialist (CS). The AMs were those folks who either had previous sales experience or were brought on board as a CS and they worked their way up.
It wasn't necessary for a CS to become an AM because BSX instituted levels of CSs I-IV. By the time you are a CS IV, you're making close to six figures. But, that takes 5 or more years and I know of only 3 IV's in the entire company. Most of these folks that make it to III or IV are previous nurses who really didn't want to get into full blown sales and have quotas.
Now, about a year ago BSX got rid of the AM position. The AM's who really showed potential had a territory carved out for them and got promoted to TM. Those who didn't, got demoted to CS.
So, now you've got a bunch of disgruntled CS's who are angry at the world for not getting promoted. They no longer really drive business, but instead are expected to cover the crap cases in the shit hospitals or reprogram the really crazy-ass people the TM's don't want to deal with. Or, if there is a major hospital in the TM's territory like a UPMC or Northwestern, the CS lives in the hospital from 7 to 5 waiting for patients to come in and get reprogrammed.
Bottom line, CS is a decent entry level position if you have absolutely no B2B or previous medical sales experience. If you stay a CS for longer than 3 years, I can almost guarantee you that no med device manager will hire you as a full rep because your resume shows that you are lacking whatever it takes to get promoted internally. Just my opinion, though.
Take the position if you meet one of the two criteria above. However, stay in NO longer than 2 years if you don't get promoted to TM and start looking elsewhere for an associate sales rep role or a full sales rep role in a smaller company.
