Pros
As a big company, it provides many resources such as training and library access to many books. It is a leader in certain medical fields.
Cons
There are too many older employees who have been working for the company for over 20 years or even more. This is actually not good for a company because new comer's opinion is often not heard by the management team and new ideas and fresh thoughts are suppressed by those older employees because they never heard about it. They are usually afraid of any changes in the existing technologies because they worry about not knowing the new stuffs. Those older employees are obstacles to innovation and they can go nowhere if they get laid off. So for innovative young people, it is not a good place to work. Also the company's culture is very bureaucratic and there are too many politics.
