Pros
If you haven't had a professional experiences, this would be a good start. Citigroup is a big name to be written on your resume. Company benefits cover most of the museums in NY and health, dental coverages are very cost effective (until 2008). Benefit costs doubled in 2009.
Cons
If you are working anywhere else but NY, there are no room for career development. You are stuck on a dead-end job. All directives are passed down from NY and there are no recourse. After two years of being a Personal Banker, your option is to become a Business Banker or a Branch Manager. Most of the bankers quite before two years. Compensation plan seems to change every quarter and upper managements in NY are trying their best to minimize bankers' compensation payouts.
