In addition to the more general behavioral questions which are likely to be asked during your interview, they will no doubt be questions asked which will be more specific to medical sales.  Some examples could be:

1)    Tell me about a situation in which you made a physician upset during your sales presentation.
2)    Describe a time which you alienated a co-worker by your actions, and how you resolved this conflict.
3)    Tell me about a time when you withheld information requested by your sales manager, or company co-workers.
4)    Describe a situation when you used creative ways to make your sales quota.
5)    Tell me about a time when you had to “fire” a friend or subordinate
6)    Give me an example of how you solved a brewing conflict with your sales manager.
