What a disgusting manager! The last one in the round. I applied through StackOverflow. Two weeks later, I got an answer. First, I did a video call with the CEO, who described the company. Then, I did another video call with a manager who talked about what his team did. I was then invited to an interview in Oslo. The interview took around seven hours, and they invited me for lunch in the meanwhile. All the interviewers were fine except for the last one: a Norwegian manager who was very rude and insulted me several times openly. He only asked personal questions (e.g., whether I have brothers or not) of little relevance for the position, nothing about C++. On top of that, he looked to really enjoy making humiliating comments on my home country.
