The first round interview consisted of a chat/competency based part and a case study. You are given 15 minutes to analyse the case study on your own, make sure to calculate profits, costs and revenues if you have actual numbers. Then it's meant to be 10 minutes of questions on it, but mine was over 20 minutes of it. Questions were quite in depth, but Fairly straight forward. The competency part also has career motivation parts, so why deloitte why tax....etc
