First, I got an email form the recruiting team and I was asked if I would work for their branches outside Stuttgart region. I answered no due some private reasons. Second, after a few weeks, I got another email and was invited to have an on site interview. The person who was supposed to interview me did not show up and another person took care of interview session. The interview went well and I got positive feedback from the interviewer who was really nice and professional at the end of session and he promised me to send me email for follow up procedure within maximum two weeks. Now after more than three weeks they did not even answer my email.
