After going through initial filters like a video, there is an assesment centre. First, there was a group "interview". It is not actually a interview. They explain how the company works (although it is not very clear) and the negative aspects such as being willing to be relocated and the possibility of being unemployed and unpaid for long time! During this speech which I found unnecessarily long, there is a staff member who is evaluating your behaviour. After that, there are two or three test: numerical, verbal, etc. And finally, three short personal interviews of less than 4 min. These interviews are with three different staff member. They ask about IT, the company and your background. Although you cannot see that, they give you red, orange or green. If you get three green you will receive an offer. If you get orange they will check your tests. If you get red, nothing.
