I applied through the career portal and had one interview with the head manager of the department. The interview was an hour and a half. He asked me about gray levels, a few questions about how to build a graph to represent what I say, and questions on how to perfect the image itself and how to make it more accurate. There were many questions about the subject.

After that, I was given a logical question about distance and how to find the closest path between points on a 3D drawing.

how the image would look on a graph. how to make the image less blurry. how to create the circle in the image as smooth as possible (some image from the machine).
