Medical Sales Question:

Firstly, you need to decide what sort of position you are pursuing. If you are going for a theatre role, then get yourself into theatre. Observe a procedure and see how the theatre team interact. Absorb the atmosphere and gauge how as a sales representative would fit in and work effectively.
You can arrange this by utilising existing contacts - perhaps you currently sell to Consultants who could introduce you to Surgeons, or you may already sell to Surgeons, just not whilst in theatre. Alternatively, speak to the secretary within a surgical unit at your nearest hospital and find out when a rep is next due that you could speak to.
If you have decided that medical disposables is for you, speak to a Practice Nurse the next time you are in a practice. Ask him/her what makes a good wound care rep, say, and what do they look for in certain products.
You will find that you learn a great deal about the market by asking a few simple questions, and this will both help you to secure interviews, and to impress at interview.
