Pros
Good colleagues/experts in their field, huge knowledge-base. Most colleagues are appreciative, respectful, and recognize the contributions of their administrative assistants. Diversity is supported (there are formal diversity networks/groups internally), active in local community, beautiful site in San Diego (La Jolla Campus) with excellent on-site cafe and catering.
Cons
Organizational changes happen frequently. Annual review process is not well managed and suffers from imbalance. Glass ceiling: incredibly difficult/rare to move from administrative support position into another role/position/career (even with an MBA). Management effectiveness/style varies by department (true anywhere); be sure to make inquiries, if interviewing (Pharma community is small, easy to gain honest insight--be sure work style is complimentary).
