Pros
New, top-of-the-range hardware, nice office, great kitchen with professional chef which is almost free, poker tournaments, great Christmas/Summer parties where no expenses are spared.
Cons
Poor communications from management, long hours are expected (say good-bye to your leisure-time), abysmal atmosphere, people being fired/let go/leaving "by mutual consent" (then escorted out by HR) all around you. Idiotic time-lines, bad managers kept in key positions in spite of poor performance (apparently it's who you know, not what you do), endless pressure, late reviews, poor decision-making, no recognition, bullying by upper-management, work calls received on personal phone at all hours, not knowing who to trust. Key members of staff let go or allowed to leave when dead wood allowed to stay in key positions.
