Pros
Great infrastructure of systems and centralised resources. You definitely notice it when you've moved on from Unisys to a new organisation. It goes without saying that on an individual level many of the people were great and I learned a lot from professionals who probably didn't realise that they were mentors or role models.
Cons
where to begin - hours, morale, poor leadership, having to go to work in the mornings with a fire extinguisher on your back because you never knew whwre the next one was going to break out. In fact, to illustrate the point, every time someone got yanked from what they were doing, or was 'stood up' for important meetings, the most most common reason given (like that made it all ok) was that they had been called to a 'fire drill' Pur-lease!
