Pros
Independence - as a NTT consultant if you are at the client location or working on a project, you are not micro managed and are not part of politics which is a norm if you were working for a company. Not much blame game either.
Cons
Company has potential to be successful, but management is not moving fast enough to implement and communicate their vision to the rank and file. All the companies bought by NTT are still operating under the NTT logo, every company is still using their own legacy system and operating independently, NTT has yet to realize efficiency gain from merging these companies. Too many layers, everyone is director and VP, although they can barely perform at that level, unqualified managers who can not handle clients properly but they all have shiny titles on their shoulders to show off. Too many competing silos, means NTT can not put an unified front for the client fast enough. Recruiters lie big time, do not believe anything which you are told. Benefits suck, medical is too expensive for the consultants, no 401(K) in the first year. Horrible HR and backend IT support system, they have no accountability.
