Pros
Decent money (but it will stop mattering soon) and even that is changing now. Research, liaison opportunities You can learn some things with speed here.
Cons
HORRIBLE people and management at AMS consulting (the IIM alumnus and all that jazz is fizz); nobody lives life here, they just earn. NEVER LEAVE YOUR JOB TO JOIN AMS CONSULTING. Keep your head down and take cues (which will be dropped to you); AMS consulting has cultivated close relationships with the establishment and people and systems that matter so work/contracts/tenders keep coming. You'll do projects for money but don't be under the impression that you are actually solving many problems. One audit by a good organisation or even a cursory observation will tell you that nothing is ok here. One review here calls them 'vultures'; go taste the poison and find it out for yourself at AMS consulting which claims to help government departments and the society!
