If I understand correctly, they had an online async test and they shared screenshots of the answers. Is that even cheating? It wouldn't even register as cheating for me... When I was at the university (not US) we had these online "tests" too, but it was a different category than the real tests. Nobody really cared what you do. Sometimes we sat down together and did it one by one (especially if it was some random generated math problem), other times we just shared the answers (when the test was too lame...)
