Hope this reply isn't too late for you. Accenture's CFO & EV consulting practice works for CFO and Finance executives on digital finance transformation initiatives (people, process & technology). Moving from traditional finance to new age finance (digital & connected).
Given you are interviewing for Strat consulting in CFO & EV, technical questions will be around your understanding of Finance- valuations, P&L, M&A, Finance Reporting, Cloud tools etc. So please have a look at their website and prepare some examples. I dont know your background/CV, so feel free to shoot a direct message if you need more help.
