I received proposal from one of Stuff agency. I sent my CV and some description of my experience and links to couple of my test projects and skill test reports. After couple of days I had interview with HR manager. She was very polite and give me some interesting details about company. After interview I received from her technical task. The wasn't so complicated, but it took some time to prepare it. I spent two days to complete it. HR manager asked me to prepare task to next interview with technical leader. I send to her link on my prepared task. I was a little bit surprised, when nobody download my task from hosting. After second interview I received denyed and check hosting again. Nobody downloaded and checked my task. Be carefully, and don't make any tasks from that company on first steps of interview at least. Don't wast you time with that company. On technical interview, I found that my opponent don't have updated CV from me. He used old CV loaded from "linkedin" profile. Waste relation to candidates told us about company more that any description on their site.
