Pros
The people that work for OpenSymmetry are generally a nice group of guys. If you are a graduate it is a very good company to learn the consultancy trade and pick up some technologies that will be very useful (SQL, XML, etc).
Cons
If you are a hard working and committed consultant who is willing to do "whatever it takes" to get the job done, then that will be appreciated......and used for all it is worth with very little appreciation shown financially. The business OS works in is enabling sales people to be motivated by money and reward. Unfortunately they don't take on this philosophy internally and consultants end up paying for a top heavy, well paid management structure. If you like watching internal sales people get rewarded for selling solutions that will give the client "more bangs for their buck" while you are expected to provide the "bangs" by working 16 hour days and weekends....then this is the place to work.
