Applied with my resumee, got an invitation a week later, the interview another two weeks later. It was a single interview of an hour for a graduate internship. The interview was short and efficiënt: a few questions about my study phase, followed by questions to test my ability to predict my behavior as a manager based on past experience and a business case. The interviewer was able to give me elaborate feedback by phone, after I'd asked for it.
Interview questions [1]
Question 1
Business case; "Imagine you're the CEO. Think of the issue 'Local Governments'." Follow-up questions were basically 'What are the strengths, weaknesses, opportunities, threats'.
