Pros
It's a decent job to start right after college to get your foot in the door in the financial industry. 3 week vacation starting first year is nice. 2 paid volunteer days is also a plus. You don't need much background knowledge- you will learn quickly from your peers on various Excel and multitasking skills. Younger workforce makes it easier to identify with and communicate with peers.
Cons
Too much OT... be prepared to work 12+ hour days or more depending on the situation, such as internal technology failures causing outages, yearly/ monthly audit, high employee turnover rate, etc. Working from home is not guaranteed; it depends on your manager and is in no way driving the work-life balance that State Street claims to propel. There is also too much offshoring of tasks to teams abroad to save money. Quality of work is decreasing due to difficulty training and communicating to teams long distance. High turnover rate makes it difficult for current employees- if you're still at State Street, be prepared to train new hires on your tasks over and over again. Office politics is not uncommon here. Hard working and smart people don't get promoted. You can be stuck in a position for years or get promoted very quickly- it's all about favoritism. Management demands are not reasonable- requests employees to do certain high level tasks, when either they don't know how to approach the problem or the problem gets blown out of proportion.
