Pros
The technology can be interesting and the coworkers can be really interesting. They really know how to build an OS there. Being able to work with a person from 4 different continents is really cool. One of the few places where a machine is constructed from the ground up and as a result you can understand computers at deeper level them most.
Cons
When someone is anointed by management NOTHING will remove that person the messianic status. Even if that person is wrong and abusive. I have witnessed a screaming match that went on for over an hour. The first level managers then attempt to hide these things from directors and above. Recruit! Very little hiring is being done and when we have a chance at top talent he sliped out the door because it took over a month to get him an offer. Further more some of the best people we have under 40 are going to leave/leaving/left because the atmosphere is very angry, very petty. Things are very weak when it comes to proper engineering. There isn't much professionalism left. Several key groups hold NO code inspections and when pressed by upper management lie and say they do. Fund things that will attract market attention. You have a sizable base with the old univac customers but they are being ignored forever. Most managers say 90% of the current customers is ok. But they keep saying that and soon after a few years 90% of 90% of 90% is not worth it. Declining sales, dwindling talent pool and weak management all lead me to state the obvious but painful. Eventually it will have to shut down.
