Pros
Great benefits, in general highly organized, excellent facilities, great training opportunities. Quality and dedication of co-workers generally extremely high. Flexible working hours and no stigma to working from home.
Cons
Challenging to get commitment to long term projects. Many legacy systems, new hires coming in from other high tech companies will find technology hasn't kept up with the times (they're working to fix this). Getting things accomplished requires getting the approval of many stakeholders - expect bureaucracy and for things to take much longer than in other companies. The company is very faction-driven through it's divisional structure - it's like 5 companies (more) rolled into one with each faction having it's own agenda. This creates significant internal politics. Recent attempts to change culture for the better are faltering - there seems to be a blind spot for managers who manage up well but have track records of managing down poorly, despite company focus and goals around improving employee engagement. That said, most Autodesk managers are excellent and supportive of subordinates. Where feasible, ask around and get insight on this before accepting a position.
