Pros
Fujitsu is coming up on 80 years of existence, so you know it can't be poorly run. Fujitsu has a deep commitment to quality, and honestly cares about the customer, from the top of the organization to the bottom, it is not just lip service. Fujitsu also cares about employees and takes a long term view of this relationship. This kind of stability is rare in Silicon Valley. Fujitsu is not about flashy new fashionable technology, but instead a deep commitment to working together and truly solving the problems that the customer has.
Cons
Fujitsu is not a hip start-up. It is a big company, and tends to move very slowly and conservatively, unable to ride the latest trends. You will not find the thrill of a high tech start-up working at the bleeding edge with the very latest, trendiest technology, but instead you will find relatively solid, conservative, and well understood technology that functions without the risk of being an early adopter. In most of the world Fujitsu is an IT superpower that everyone knows about, but in America Fujitsu has a special challenge in that it is relatively unknown. This clash inhibits the kinds of publicity stunts that smaller, hipper start-ups use to market their products. As a predominantly hardware company, software is another area that presents a challenge.
