Pluspunten
Despite Mercks size, working within a particular brand gives a sense of a small personal environment where one can direclty generate meaningful contributions. People are quite helpful if you just ask, and in general it is fairly easy to gather the necessary support to execute an idea so long as you are able to clearly present its benefit to the company.
Minpunten
There is a significnat lack of visibility into what other products are being developed, and ongoings within the company that can leave one feeling quite silo-ed. On the managerial side mid level managers are quite poor people managers, especially in the technical areas, that do not promote employee development, leaving the employees with a lack of purpose and unclear future.
