Avantages
Solid benefits and compensation packages - very nice facilities and working environment, and a general feel of other employees valuing each other (generally more than management). Have a fairly well defined market space (but that can be a negative too).
Inconvénients
Poor organizational structure dynamics - i.e. intern in-fighting and attempts to define value at the expense of other teams leads to some strained partnerships across the company. Also, the IT infrastructure supporting the company is sadly inadequate and not efficiently managed or executed on (this is for both internal systems and product offerings). Everything seems to take longer and be harder because of the cyclical nature of some of the key businesses (i.e. can't do anything in the datacenter around tax times, etc).
