first step: I had the small chat with the HR representative. second step: I had a technical call with two persons. third step: I received the task to do at home. The task require to use many web technologies and to complete the task many hours were needed. I work on it 20 hours and I only manage to made a core. After sending my solution for the task, fourth call was proposed. We set the date for the call and then I didn't receive the call and all my attempts off contacting fail. This very unprofessional way to refuse an application. I expected at lease to get the feedback about my solution for the task.
