“Why Accenture rather than a pure-play strategy firm or a boutique technology house?”
What they test. Specific, researched motivation
Weak answer. It is a huge global company with a great culture and I want to solve complex business problems.
Strong answer. Distinguish Accenture by its end-to-end delivery and reference a specific US project (a retail cloud migration or healthcare transformation), then connect your major or technical projects to that service line.
