I interviewed with the office in Düsseldorf. Overall the process was good, until the feedback. The first part of the process which included several telephone interviews was very well organized. The interview partners were interested and provided good insight to the company. The interview in the office was good as well... CV, case studies, questions on my side. I was told to receive feedback after a couple of days. When I asked for feedback after a month, I was told that HR had called me to tell me they couldn't offer me a position because I didn't have consulting experience. I was very surprised because nobody had called me (I actually double checked my voicemail and calling lists twice) and because I have been working in consulting since graduating from University. I told them so. HR promised to put me directly in touch with one of the interview partners for the feedback which they never did. I wrote him an email and he promised feedback after his holidays. When I wrote to him again, I never heart back. Therefore the good experience during the interviews was ruined by the bad handling of the feedback which I consider an important part of the process.
