Zalando Logistics Software Integration Testing Project Manager interview questions

The entire process lasted for 5 weeks with cancellation of interviews in between. I had a total of 5 rounds . After the 5 rounds, to me it seemed like I made it however I just recieved an auto generated email with no feedback saying I was rejected. I emailed asking for a feedback because i had invested my time in those interviews. But there was no response. As most of them have written in their reviews, people working in this company are arrogant and very mean. This was my worst experience of all.
