There were 4 interviews in assessment center, 2 technical and 1 competence and a team interview and it takes me like 5 hours, HR and interviewers were nice. Competence interview and group interview were very general. The first technical interview asked me to write code in papers but the question are easy, like create a class and getter setter method in java. And the second technical part came to some harder questions and they would ask you some question based on your CV. I have been rejected.
