Has this interview been shared here before?
It's a long interview, transcribed in the comments, with one of her first coaches in Moscow, Igor Lyutikov. The comments are, alas, out of order, from what I can make out. However, the interview covers her work ethic, her early ability and talent, a story about her doggedly running thirty laps of the stadium next to the ice rink at the age of eight, and bullying she was subjected to by her peers, which led to her changing coaches.
It also led me to the video of little Kamilla skating to The Swan, by Saint-Saëns, aged eight.
