I agree with KJ, Rambo and all other people - personally, I don't think it's a good idea to join a company that doesn't respect your skills and experience..
Secondly, let's consider that we keep the emotions apart - supposing you join them, and the same scenario continues (which is more likely - based on many opinions already expressed in this forum - they have one of the worst work cultures, lots of politics etc.), just think if you'll be able to cope up with this kind of culture. If you have no problems with the people around you, if you can shut yourself from them and just continue to carry on/ concentrate on your work only - then go ahead. Accenture as a brand will definitely help you... (My personal experience about their interview too hasn't been that good - it's one of the worst I have had till date)...
And just another perspective to Zilbu's comment -
and remember years back when a tall guy applied for an announcer in a local radio station, he was rebuked by saying "go n sell apples, ur voice is not good at all", that guy was Amitabh Bachchan.
The guy was rejected at the interview for the radio station and did't join the radio station! Had he got through to the radio station, the world today would have missed a legend called Amitabh Bachchan, to some unknown radio announcer
So, just decide what exactly you want and then finalise about the offer cooly.. All the best
