To enter the consulting division of the companies you mentioned you do not need an ACA qualification. Actually, very very few people I know in these companies are qualified. (remember, this is only valid for the consulting arms - not tax, audit, brs etc)However, by gaining experience in IT at accenture you might be going in opposite directions. You should try to change asap - perhaps EY - which are recruiting heavily, or try and land some high level consulting projects with Acn. Stay away from integration
