I applied online. The process took 1 week. I interviewed at RT-RK (Belgrade, Central Serbia) in Mar 2019
Interview
First you have a casual talk with HR and the general manager about the company, its teams and what they do. They ask you about yourself and what you are interested in, to find a suitable team for you. Then they give you an intelligence test. After that you have a technical interview with a team lead. Technical interview consists of some basic questions.
