I had a first interview with a recruiter. It was a short chat about my motivation and skills. Following this, there was an interview with the hiring manager. We talked about the role and some prospective projects. I actually had a very good feeling, but I have never heard back from Zalando after that. My emails to the recruiter remained unanswered (several months now). From this experience, the hiring process at Zalando does not seem to be very transparent and respectful.
