Business areas vary and include sales and marketing, consumer divisions, global manufacturing and supply, research and development (R&D) and the usual corporate divisions.
Each of these areas is likely to be a hub for different cultures. For example, R&D has a culture focused on exploration, predominantly consisting of scientists and physicians seeking scientific opportunities to translate into medicines for the future.
An understanding and appreciation of your specialisation, coupled with a good work ethic will get you in the door. After that it definitely is what you make of it.
