Deloitte Management Consultant interview questions

My first interview with Deloitte was an initial phone interview with HR about why I was interested in Deloitte, consulting, etc. The second round of interviews was 2 1:1 45-minute phone interviews. The first 45 minute interview was an over the phone case study. Not too bad nothing unexpected came up. The second 45 minute interview was a behavioral interview (always stress the benefits of diversity in the workplace, show that you can handle potential issues that commonly arise in the work-place, talk about how you work well with people, and be able to give EXAMPLES for ALL of these types of questions. Last interview was with a partner and director at the firm. Overall good experience up until that point, but after trying to contact HR as to why I didn't make the cut, I couldn't get a hold of them. Go figure.
