Good potential for long term career prospects in terms of experience but slow career progression and low pay.
Pros
Good people and friendly place to work. Potential for good experience and to take on responsibility at an early stage in your career. Experience of the full project lifecycle and client facing work with the possibility of moving to other areas of such a large business.
Cons
Recent salaries low in comparison to similar jobs elsewhere, particularly in Analytics roles. No clear salary bands so secrecy surrounds the pay of colleagues and no clear idea of what you may be earning in 4 years time. Reluctance to promote in lean times with the focus on the individual proving they have earned an average review rating. Reliant on your line manager and relationship with them for prospects (as anywhere I guess!). Prospects likely to improve when the economy picks up and money isn't as tight.
