On one of the Android meetups I got an information that Zalando is going to hire 10 Android devs at onse, so I thought it could be my chance. I applied online. Week later they sent me link to calendar to schedule HR screening. Next possible date was 3 weeks later. So, just to speak with HR you need to wait 4 weeks. I don't think such a huge company as Zalando can't find 30 minutes of any available recruiters sooner than in 1 month.
But, anyway. I know, that it's a Germany, you must wait in Germany. But it should be something worth waiting for. But, not. I am spending my time, preparing to call just to know that they have some technical issues. I proposed to make a phone call. No, she said "tomorrow". And disappeared for next 1,5 weeks.
Next time I got a letter from them I said I call off my application, because I already had 2 job offers.
