I see. The take home assignment is not a test or exam, per se. It's code sample that responds to one of 6 coding tasks. We expect something around ~100 lines, typically in C. The candidate leads a code review of their code by the team when they return for the second 2 hour interview. The code review usually takes about 45 minutes. The remaining 1:15 is 1-1 interviews. So we can assure candidates that someone reviews the take home assignment as they lead that review.
