I haven't faced such a terrible attitude toward candidates before. Initially, I was told that the whole interview would be an hour talk. When it is over after several days instead of the result I got a suggestion to make an additional task that wasn't mentioned before. I sent the task after one day and they told me that I'll get the feedback in 1-2 days. I waited for one week and wrote on my own. They were sorry and promised to call me tomorrow. And then nothing. I asked them again and got ignored. I hope the rest company departments work better.
