Pros
Nice views from the 28th floor. Occasional work-mandated fun was actually fun.
Cons
Nepotism and inexperienced staff. Constant ask of the IT department to perform actual architectural work. I was once told by HR to that they saw an unplugged lamp in the president's new office and to go fix it right away. The IT department has nothing to do with desk moving and lamps or anything that plugs in besides your laptop and occasionally a printer (which there's also a separate department for). Similar things happened multiple times. Eventually, a friend of a friend from someone higher up was brought in to gut the department, lie to everyone, and bring in her own staff. Progress!
Parts of the marketing department are literally incapable of performing their jobs without extremely specific (and not good) hardware.
Older staff is often entirely capable of basic computer functions like renaming files or copy/paste using shortcuts, meaning most of their time is spent doing essentially nothing of value.
My experience was that the lower end staff was ALL overworked, the higher end staff had massive egos with a few notable exceptions, and the company was a huge listing ship thriving on occasional waves of income from mostly foreign projects which failed to ever materialize (though we did get paid).
