There are 2 steps for the position: 1. Personal interview with HR and a director from the department. 2. Assessment center. The Assessment center includes personal interview, group discussion and role play. We were 8 and only 3 people can get the position. Personal tips: For the group discussion, you need to stand out and try to lead the team. Since this is a sales position, being charming and confident is really important. For the role play, you need not only solving the conflicts in a structured way but also show that you are really passionate to solve it. I was so calm and structured for the role play that they think I am not passionate and qualified enough for the position, although I believe I am fully qualified. Overall, the atmosphere was friendly but I am not so happy that at the end all candidates got phone calls (including not chosen ones) for suggesting another internal positions and I am the only one who only received auto generated rejection Email.
