Deloitte Manager interview questions

Long winded. Terrible communication. Recruiter did not want to have a call prior to final stage, so would have been left in the dark. After being very tactful, spoke to the recruiter to ask about feedback from previous rounds and what to expect. Said previous rounds were excellent and final round is just a cultural fit, very few people get to this round, well done etc. Still prepped thoroughly for final round and now i know the partner was clearly looking for certain answers that i was not privvy to. Completely sold a dream. Don't know how someone gets thru 2 case studys to be told 'technical' skills are an issue. BS
