Pros
State Street as a company encourages growth and development. While working for State Street (in relatviely junior roles) they have taken me from working in London, to the headquarters in Boston and now to Sydney (my original home). I now have a regional role in a field completely different from what I started my career in and this is all down to the development opportunities I have been offered. My manager is supportive in terms of flexibile work arrangements and I currently have the option to vary my start and finish times, work from home and compress my work week when neccessary.
Cons
As it is a global company, and as I work on global initiatives, there can be days with long hours, especially when dealing with global conference calls. Unfortunately the Asia time zone always seems to come out worst! Mindsets can be very Boston-centric at times with many initiatives having a strong US bias. Turnover can be a bit of a struggle in Asia, having a knock on effect - the worse it gets, the harder it is for other staff members to keep on top of things, leading to more turnover. That said, it does create opportunities for others who want to move upwards.
