"When interviewing pharmaceutical sales representatives, employers are looking for candidates with expert sales skills accompanied by a strong knowledge of pharmacology. Expect to answer a mix of technical questions about the uses and effects of different drugs as well as sales questions how you would go about marketing them to doctors. Although not mandatory, receiving certification as a Certified National Pharmaceutical Representative (CNPR) will ensure you walk into interviews with a competitive pharmacological background."
I was asked to prepare for a clinical review but in the interview I was asked to sell off a brochure that I had never seen before.
I looked at the opportunity of a way to apply my previous knowledge as well as an opportunity to see how my prospective manager would coach me. It went well and we both learned a great deal.
