Pros
Diversity is huge there so you get to meet many different people. The company is well-respected and you can take pride in knowing the products you make are helping to save the lives of others. The company also particpates in a 360-degree feedback process, so you get more than one person rating you and providing you with ways to improve your work. The company also has numerous facilities both within the U.S. and abroad so there is a lot of flexibilty and freedom to explore many different places. The company will also pay for relocation fees as well. Overall, it's a good place to work.
Cons
As with many company's Johnson & Johnson is extremely political. First impressions really are everything. If you don't get on the good side immediately of all persons met, you are going to have a hard time advancing. The problem is that everyone within the company knows a lot of different people and they all talk; therefore, if you've made a bad impression on one person, other people are going to judge you immediately based on that one person's feedback before they even know you. Johnson & Johnson is very demanding. As soon as one quarter close is over, you're already supposed to have been working on reports for the following quarter. It never feels like you can get ahead.
