Interviewer was not at all friendly, he was not interested in the interview, he asked questions about osi layers and functionality of each layer, how does session layer maintain session logs, difference between tcp and ip

The first interview included common personality and culture questions. It was held online and lasted 30 minutes. The following interview was a face to face technical one. We discussed what the team is focused on, the programming languages and technologies used and what they look for in a junior developer (eager to work, interest in telecommunications).
