3 out of 3 optimization/architecture, very well 3 out of 4 algorithm problems 0 out of 1 3d math problems. Feedback was non sense. They said optimization/architecture was "low", algorithms "medium" and 3d math not attempted. Apparently 3d math had a section of its own, but the problem itself was only worth 10 points (max was 100 pts). Also they say low level/architecture knowledge was weak yet I've even used assembly to show how some things work (and went into great detail on some topics while staying concise) - the questions were easy without exception on the low level (I've worked 3-4 years in embedded low level and almost 1 year in compiler). I said to the recruiter the feedback is wrong - makes no sense. She said that, it's impossible, the process is very well done and she can't do anything about it.
