First I was interviewed by HR manager where I got some general questions about my education and experience, then I had a teechnical interview with three developers that lasted about 40 minutes. I cannot say I was excellent at it since I had previously no working experience with Python, except during my studies. The interviewers were very kind, they answered and tried to explain everyting that I had trouble to do so... Also, they listed every competence they expect from a candidate and even said I would be welcomed to apply again after a few months if I learn and gain confidence to do so.
