Pros

Good compensation, stable industry, a pension, generous paid time off if you can afford to take it, great location. Big-company technology in a small company forces staff to have multiple skills. After the multiple rounds of cuts, IT is getting more efficient in many areas. Management in some areas are excellent.

Cons

80% of the work is done by 20% of the staff. Very difficult to get promoted, priorities shift daily, long term strategic planning next to impossible, and many highly paid / highly titled employees in the technology planning area don't pull their own weight. Working hours very stressful. 6-day work weeks are common.

Pros

Strong engineering culture with exposure to large-scale financial systems, distributed architecture, and production-critical platforms. Good opportunities to learn modern cloud, performance, and reliability engineering.

Cons

Bureaucracy and internal politics can sometimes outweigh technical merit. Employees who take ownership or challenge inefficiencies may face delayed recognition, unclear growth paths, and shifting expectations, leading to frustration and disengagement over time.
