Cons
In my 15 years of IT career, I did not work in such a negative and highly political environment. The "power" is concentrated in NY and London and the people who are working there for ages do not want you to succeed. The so called architects or managers do not have idea about the current technologies and are not open to any new idea/suggestion and feel threatened, Most of the managers in NY really treat really bad, yes this is true. The same goes with their preferred vendor who's not ready to share knowledge and would treat you like an enemy... The recruiters may promise you many things like green card processing/perks/work from home etc and after joining the company you'd get a shock !.. most of the recruiters are contractors who use companies email id and give you impression that he/she is from HR, do not fall for it. I know at least 4-5 people who left the company in first 3-6 months that speak about the culture and environment which is very political.
