Not enough space to list out, but will try
1) no raises over 5+ years
2) incompetent managers in BDS in N. America and Europe
3) run by former HP people who were all fired by HP and brought their terrible process and procedures with them over here to the point is has choked everything to a stand still.
4) outsouced as much of the client security managers to India and Mexico as they could get away with and fired as many US CSMs they could get away with unless the client complain, all due to a "contest" with other units to save money instead of actually trying to grow the business
5) So so many level of managers, sr managers, directors, sr directors, assoc direcotrs, AVP, VP, SVP, EVP,...well, you get the picture, titles handed out like candy and are worthless. 99% are the people have no tech knowledge, just paper pushers.
6) Tools, or rather lack of tools, instead of actually investing in tools, they create low homebrew knockoff tools like MAIA (their finanace forecasting tool) and ART (knock off eGRC) and tons of other pre-2000 tools which leads to #7
7) Their main clients are bottom dwellers who have already made the outsourcing run through IBM, Cognizant, Tata, HP, etc and burn their bridges and landed at Atos which the the choice of last result which leads to #8
8) All their clients have legacy tools and systems, think windows2000, XP, outdated software, apps, network equipment, etc. If you are looking to work on anything before 2005 this is not the place for you
