Overall interview experience was ok. I enjoyed talking with the Zalando employees, however sometimes it was not a conversation, rather the list of questions which you are expected to answer, so pretty one-sided. With other folks it was quite an interesting conversation.
What I highly disliked was the HR communication. I think it was one of my worst experiences so far, and I genuinely wonder why Zalando doesn't invest in it. Having my emails ignored for days, having received the wrong auto-replies saying "you are no longer considered for this position" and then 5 min after "wait, you are continuing further on" without any explanation or a follow up. I find it very poor. It neither gives an overall nice impression of the company nor a positive hint on how they treat their current and future employees.
