I applied by a link from recruitment agency. After quick call with recruiter I got a link to external service to check my coding skills. There were a couple of tasks I had to complete within given time ~ 1 hour. Some of tasks were easy and some were tricky and difficult, because it was difficult to understand description. I completed all of them and submitted results. As I was said, there was some code review and eventually they just disappeared. Recruiter does not respond in skype and I don't have any feedback. NOT PROFESSIONAL.
