Ventajas
Pfizer is the industry leader and its global reach allows colleagues to experience a great deal of work diversity. While the glory days of the pharmaceutical industry were the late 1990's and early 2000's, Pfizer will continue to be an industry powerhouse. The company is diverifying its core pharmaceutical approach by expanding into biotech, and reorienting it's sales and marketing force away from product-based approaches to customer-based strategies.
Desventajas
The industry is in the dumps and Pfizer is going through a particularly tough time; a hangover from the roaring 1990's. As a result, some talented leaders have left (or been asked to leave) and many of those left are overwhelmed. I think this is a temporary solution, but the cost-savings exercises we are experiencing has taken much of the fun out of working for Pfizer. If the salary and benefits weren't so good, I probably would have left already.
