Cons: no work\life balance, you are forgotten (read my review)
NTT Data (formerly Keane) is one of the worst IT consulting companies to work for.
I was unlucky enough to work for them in Vermont.
Basically, they pay a little above average but their work\life balance is terrible. I was an IT Manager for a healthcare giant and I was working 24\7 at their adamant orders.
Finally, after 8 months of torture and one of the worst Christmas holidays I ever experienced, I simply stopped showing up for work. What was interesting was that I still getting paid, full salary!
They discovered this after my seventh paycheck was cut and they called me directly stating that I have been let go, etc.
The funny thing was I had already started a new job and I still received my vacation pay. Lol
Bottom line, they are too big for their own good.
