This seems odd to me because the result would be obvious, unless Amazon is turning a blind eye to it. If a team has thirty members, hires three, and fires those same three by the end of the year, that's suspicious, but obviously they could just have had a bad run. If it happens three years in a row, or happens on five out of eleven teams in a group of 300, then that's a real problem. But Amazon would have to be blind not to notice.
