I worked for 4 years at Accenture in the business consulting practice (organization and change management, then org strategy). I am in business school at Dartmouth (Tuck). Your GMAT score, accomplishments in SITE, and self-awareness will make a big difference. It is odd: my friends in the SI&T practice, from the same college, with virtually identical numbers, were rejected. I think they like the management consulting and strategy people better.
