Pros
Basically none. I will say that on an analyst level, many coworkers are friendly, nice people. The team that manages the dow account actually is made up of some smart, good guys.
Cons
This review is specific to the institutional fund accounting team, I can't speak for the rest of Northern. There is absolutely no reason to accept a role with that team. Management is a Dilbert level of incompetent, the office actually functions better when they are not there. There is no room for career advancement. Pay is bad compared to the industry. The hours are terrible, it's not unusual for all the analysts to still be in the office past 9 PM. The job teaches no transferable skills. Everyone is trying to leave. Turnover in six months was above 50%. Upper level management is working on automating most of the department. Management does a terrible job communicating, I remember a coworker who had been there almost two years getting yelled at for approaching the bosses cubicle without sending an instant message first, and that's just the tip of the iceberg. Things just get worse.
