When I applied for an internship, by mail an assignment was sent. I resolved it and the date for the technical interview was set. The interview did go very well, I was interviewed by two developers of the company. Pretty much the interview was ok, I was asked about the core concepts of programming and I was asked to explain the assignment in steps. The guys were very friendly and the interview lasted for an hour.

There is no hr interview. First you solve a task at home which you later discuss in the interview, then another task is given and you need to solve it on the spot implement oop principles,
