Pros
Colleagues who work closely together tend to get along well; generally a pleasant place to work. Managers tend to work well with their direct reports and advocate for them strongly within the bank. The bank culture, in theory, values individuals and their contributions. It's a lean organization, so if you have a job here and perform it well, chances are your job security is solid. Hours are flexible, depending on workload. Hires/promotes from within.
Cons
I'm an entry-level employee (maybe slightly higher), and I'm already under pressure to work very long hours and weekends when workloads are heavy (which they often are). I only see this getting worse as my career progresses. Upper management are only seen to appreciate sales staff - internal awards are almost entirely sales-oriented, appreciation newsletters only focus on sales' contributions, and explicit promises of appreciation (e.g. team lunches with senior management) have gone unfulfilled.
