I have never understood the three major occupations recruited by pharmaceutical companies. Can anyone tell me?

The marketing manager is from the marketing department. He should take a macro view of the market in all regions of the company and formulate reference marketing plans and marketing analyses.

Academic Promotion Specialists are personnel trained. They mainly train product knowledge and conduct some training for new employees who join the company. They also have some additional tasks, including attending department meetings.

Pharmaceutical clinical sales representatives are terminal marketing. Introduce products, indications, precautions, specifications, usage and dosage, etc. to doctors, conduct clinical promotion work, and on the other hand, feed back medication information to the company.
