There are three rounds. The first round is a personal interview with the company director. Second round consists of a technical challenge to be solved. Third round: presenting and discussing your solution to the technical challenge together with the technical team and the company director. I dropped out after the first round. During the whole process the job offer was constantly changed and new required skills were added, as if the could not decide on the profile they were looking for. For me as a candidate this was super frustrating and annoying. During the whole interview I felt like being talked down to by the company director.
