I applied online, got a phone call and brief telephone interview with the HR person who then invited me for an interview which took place a week later. The interview was 1 hour including 15 minutes for completing a written task. The atmosphere was very friendly and very relaxed. After the interview it took 1 1/2 weeks until I got a call from the HR person telling me I didn't get the job and forwarded me the feedback from the interview panel which was very helpful for future applications.

There's not exam but a face to face and one to one interview conducted by the team leader. As the position is for graduate, no technical questions were asked. Instead, the interviewer wanted the candidate to show their thinking by asking a lot of opinion questions.
