Planet Project Manager interview questions

My submission was rejected without any notification for the reason to be rejected. I was very surprised that they don't have any contact point to answer your questions. Previously, one year ago, I went through 3 interview steps and finally they rejected me without any information. I spent lot of time for preparing and the minimum would be to giev at least a motivation for rejection

There are four interview steps. Two with HR and two with operational functions. The first interview was not too long (30 minutes) and only about my background and my motivation.
