The company contacted me through the University. The first step was an HR interview, quite straightforward questions - why deloitte, what do you know about the company, CV background check. Then there where some testes - personality questions and two essays (one in the local language and one in English). Heard back from them 1 month latter.
The second stage was a business case (it was for the consulting area). It was a whole day in their facilities with a group of 8 people and we had to come up with a solution for an acquisition in the retailing industry. Again, heard back from them in 1 month.
The third stage was an interview with a partner from the field. The interview had 3 small cases with "what would you do" questions. They were mostly focused on a company's internationalization to Africa - how to avoid risk, which portfolio to bring to the country etc. Heard back from them 2 months latter.
