You think the assessment will be IT based??!! Hahahahaha, uhm, no it definitely won't be IT based. This is BAH you're applying to, not Accenture.It will be strategy based, quite possibly to do with market sizing and entry. Show them that you have common sense and enjoy solving problems. Think aloud and work through the problems logically. It's a 2-way conversation, not a "grilling". And make sure you take a shower and get a haircut before you leave home, kiddo.
