That was among one of the most unprofessional inteviews I ever had. The first round was with HR, secon round was Technical which was pretty easy and I responded all questions correctly and they replied with very postive feedback. The next was with the CTO after 2 weeks. I answered all questions and I thought It went great but after couple of weeks they rejected my profile withou any reason. It's totally waste of time. They don't even have a process or agreements among themselves.
