Very friendly and relaxed. First part "technical" with an IT consultant. We talked about my CV, what I've done, how what I've done and learned relates to being a consultant and in the end I had to analyse a piece of java code. Second part "getting to know you" with the HR responsible. Usual strengths, weaknesses, and teamwork related questions, however all phrased in a way that I couldn't just say my prepared answers but had to think a moment to fit the answer to the question. (See interview question below. That was the "weaknesses" question.)
The separation of the interview in two parts is a bit awkward as you don't know whom you should ask which of the questions about the company that you prepared. I endend up forgetting to ask some.
I did not get an offer, asked for an explanation and got a very nice email.
