Let me give a charitable and slightly less negative interpretation:
It may have looked like the applicant had someone else do the take-home assignment for him.
That said, I imagine that they could have interviewed in a more constructive way that may have been less stressful (e.g., walk us through your thought processes as you completed this take home assignment — most frauds can’t do this convincingly).
The company definitely could have done better. If you have someone hitting a home run on a take home assignment, at that point a no-hire decision better have some very strong justification behind it.
I went back and looked through my emails with them. When I asked why they rejected not only did the cite the interview questions as a problem they didn't like that I was vague in response to "What is your GPA?" I had responded "Average"
