Hi,
It depends on what they've told you would have. When I worked at Accenture I've seen 2 types of interviews:
1) Case interview with the manager
- No clear guidelines for cases, so the case depends on the manager
- 60% chance that it will be marketsizing
- 40% chance - profitability and general frameworks
- Interviewers are less demanding than at Big3. unless you meet an ex-big3 consultant as an interviewer
2) Assessment center
- You will be in a group of 6-10 other candidates
- You'll have a case (general business problem though with various aspects to look at, i.e. marketing, supply chain, finance)
- The main goal is to discuss the case together and come to a collaborative solution
My advice for the assessment center:
- Don't take a leadership role trying to organize and manage other people unless you are a 100% natural leader
- Act rather like a contributor with: a) frameworks to structure the problem b) rough calculations c) Industry / functional knowledge (it helps to be a background in marketing or supply chain) d) creative ideas
- Be nice and friendly with everyone and don't try to show that you are better than others. Rather impress with contribution and impact
Best
