Pros
Some good people in a good (probably soon to be vacant) building. Central location. Decent work-life balance. Pay scale within range for the industry and city. Good place to gain some short-term experience in the industry.
Kontras
The industry is flat, and declining in London. Commercial pressures are causing work to move off-shore, mainly to the far-east or Canada. It is no fun to work for a company which is smaller than it was 10 years ago, and getting smaller all the time. Long-serving top management have shown little or no ability to turn around company fortunes. Repeated attempts to develop animation capabilities have failed. Management actively encourages infighting amongst staff, because 'the cream will rise to the top'.
