The first step was call, recruiter was prepared and professional. Recruiter asked me whether I know company and the application itself. Later asked me couple of questions. After the call I received mail with code challenge, which was rather simple. I messed up totally this challenge, and got declined 2-3 days after submission, but without feedback. However I send email to recruiter (no response) and to tech-person who was reviewing my challenge, and I received apologies and feedback about my task. Overall very professional.
