Deloitte Strategy Consultant interview questions

It took me 4 weeks. I had a math test in the Barcelona office. Right after a quite straightforward interview with the HR about my CV and academic background. Finally I had 3 case interviews, with a Senior Consultant, Manager and Partner. Each of the interviews had the same structure, 15 min of personal and background and then a 30 min business case long testing my numerical an probelm solving skills.
