I might take into consideration rapid rise in ratings, and even this chess.com report, but please, this argument about post game interview is pure nonsense. It is not a 'tell' in the slightest. Any player with at least IM title will give you a decent analysis of that position if he wants, and Niemann is certainly better than IM even without alleged computer help. He was visibly disinterested in the interview and it was conducted in a rather hostile manner, so it is perfectly understandable that he probably just wanted a break and rest.
It’s definitely evidence just not very strong evidence on it’s own. Combined with a history of cheating and a few other tells and things look rather damming.
