Pros
Innovation, creativity, a willingness to try new things and stretch themselves to meet a goal or to be inventive. A very competitive environment but also very focused on teamwork. People get very focused and want to succeed. Lots of communication and connecting. Pretty good work/life balance most of the time. Working out and outdoor time are encouraged with great facilities.
Cons
Very competitive environment can be draining. Can be over intense at times. At times can be very much about "who you know" in order to get ahead... but not that bad. "A" type personalities abound which can be a good and a bad thing depending on your point of view. Pay is "just OK." Other companies pay a little more. Nike's stated goal is to be in the middle of the pack on pay. Pay scales and when you get raises, etc... is overly secretive.
