After submitting your CV through the official site, in case you seem fit they arrange for a 30 min phone interview. They ask about your education, your motivation, basic stuff, and how you would imagine yourself in 5 years. If you were OK then you take a logical/numerical/verbal test. In case you succeed you get invited to the Assessment Center, with around 5 other wannabees. The focus is on teamwork, presentation, basically selling yourself and the brand. They are looking for characters, so go ahead and be bold. It is the last stage before the offer, no face-to-face interrogation after it.
