Ventajas
On the whole - all the people with whom I work closely are really 'likeable', professional & supportive. The working culture is very good in terms of consultant & management knowledge-sharing & collaboration, and organizational transparency. Plus everyone I have encountered are very helpful & non-competitive (and I have definitely seen the other extreme in other companies I've worked for). Also, there are a lot of choices for benefits offered (use a newer consumer driven health plan - Lumenos - through Blue Cross Blue Shield, which is quite comprehensive & cost effective).
Desventajas
Structure is lacking - company has been transitioning constantly & is not very well organized. I have been a part of several of these major organizational changes since I joined 2.5 years ago: (1) the acquisition of 3 smaller consulting companies; (2) company downsizing (bench surplus); (3) replacing poor top management; (4) employee retention issues; (5) and soon to be merging with its sister company - Fujitsu Computer Systems.
