Having a firm offer from the firm, you should really be very clear about what consulting entails at Accenture. I can understand your concerns about joining a big co. My recommendation is to build your network as soon as possible and not to be very focussed on driving all your actions towards increasing your performance metrics. Everything at Accenture sort of centres around the bi-annual assessment process.As for the learning curve, expect a steep one if you are coming from a pure industry role.G'luck
